The new quantity demanded will be 300 units when the price of the good decreases to $45.

To use the midpoint formula for calculating price elasticity of demand, the following formula is applied:

Price Elasticity of Demand = (Q2 - Q1) / [(Q2 + Q1) / 2] ÷ (P2 - P1) / [(P2 + P1) / 2]

Let’s solve the first part of the problem: Suppose the price of a good X increases by 10% and the quantity demanded of good x decreases by 5%. What is the price elasticity of demand using the midpoint formula?

Percentage change in price = 10% = 0.1Percentage change in quantity demanded = -5% = -0.05

Now, substituting the given values into the formula above:

Price Elasticity of Demand = (-0.05) / [(100 - 5) / 2] ÷ (0.1) / [(50 + 50) / 2]

Price Elasticity of Demand = -0.05 / 0.975 ÷ 0.1 / 50

Price Elasticity of Demand = -0.05 / 0.0195

Price Elasticity of Demand = -2.56 (approx)

Therefore, the price elasticity of demand is -2.56.Suppose the price of a good is $50 and the quantity demanded is 100 units. If the price elasticity of demand is −0.5, what will be the new quantity demanded if the price of the good decreases to $45?Given, Price (P1) = $50Quantity Demanded (Q1) = 100Price Elasticity of Demand = −0.5Price (P2) = $45

Let’s calculate the new quantity demanded:

Price Elasticity of Demand = Percentage change in Quantity Demanded ÷ Percentage change in Price−0.5

Price Elasticity of Demand = (Q2 - 100) ÷ (45 - 50) × 50 / (Q2 + 100) / 2

Simplifying the equation, we get:

-0.5 = (Q2 - 100) / (-5) × 25 / (Q2 + 100) / 2

-0.5 = (Q2 - 100) / (-5) × 50 / (Q2 + 100)

-0.5 × (-5) × (Q2 + 100) = (Q2 - 100) × 50

-2.5Q2 - 250 = 50

Q2 - 5002.5Q2 = 250 + 500 = 750Q2 = 300

Therefore, the new quantity demanded will be 300 units when the price of the good decreases to $45.

Firm 1 will produce 45 units, Firm 2 will produce 45 units and Firm 3 will produce 45 units.

Firm 1: The output level that will maximize the profit is the one that produces the highest difference between revenue and cost. This can be calculated by taking the derivative of the revenue and cost functions and equating them to zero. Doing this, we get:

Revenue: R'(q) = 180 - 4q = 0 => q = 45

Cost: C'(q) = 40 = 0 => q = 0

Therefore, Firm 1 will produce 45 units.

Firm 2: The output level that will maximize the revenue is the one that produces the highest value of revenue. This can be calculated by taking the derivative of the revenue function and equating it to zero. Doing this, we get:

R'(q) = 180 - 4q = 0 => q = 45

Therefore, Firm 2 will produce 45 units.

Firm 3: The output level that will maximize the employment, L, subject to the constraint that revenue must not be negative is the one that produces the highest value of employment.

The correct options that are typical of the concrete operational stage, according to Piaget, are as follows;It involves logical reasoning and Abstract thinking is not yet developed.

The concrete operational stage occurs during the age of 7 to 12 years. In this stage, children have developed the ability to conserve (i.e. understand that the quantity of a substance remains the same despite changes in its shape), and decentration (i.e. consider multiple aspects of a situation). Moreover, the children also begin to understand the logic and organizing events in their mind in logical steps. As a result, they develop the ability to use logic and reasoning to solve problems.

However, children's thought process is still limited to concrete, real-life situations; thus, abstract thinking is still not developed. The children's thought process is still affected by their present experience or the sensory experience they had in the past; thus, their thinking is more centered on themselves and not egocentric.

The major social, political, economic, environmental, and technical barriers for national clean energy standards are as follows:

Lack of awareness, knowledge, and understanding of the importance of clean energy and its potential to reduce greenhouse gas emissions. People may not understand the urgency of the problem and how it affects their daily lives, making them less likely to support policy change.

Political polarization and competing interests, particularly in the US, make it difficult to create consensus around energy policy. Fossil fuel industries have a lot of political clout, making it difficult to create policy that is not influenced by their interests.

The cost of transitioning to clean energy is a significant barrier. It requires a significant investment of capital to build new infrastructure and to transition from fossil fuel-based power to clean energy.

The development of new technology is required for the transition to clean energy. The technology needed to store and distribute renewable energy is still being developed and requires significant investment.

Fossil fuel extraction and use have negative environmental impacts, including air and water pollution, habitat destruction, and greenhouse gas emissions. The effects of climate change, including more frequent and severe weather events, threaten to exacerbate these impacts.

The effective interest rate paid by the engineer for the loan is 17.09%.

To calculate the effective interest rate paid by the engineer for the loan, we need to take into account the interest rate on the loan, the loan-default insurance cost, and the loan setup fee.

The interest on the loan for one year is calculated as follows:

interest = principal * rate

interest = $27,500 * 11%

interest = $3,025

The cost of loan-default insurance is 5% of the loan amount:

insurance_cost = principal * insurance_rate

insurance_cost = $27,500 * 5%

insurance_cost = $1,375

The loan setup fee is $300.

To calculate the total cost of the loan, we add up the interest, insurance cost, and loan setup fee:

total_cost = interest + insurance_cost + loan_setup_fee

total_cost = $3,025 + $1,375 + $300

total_cost = $4,700

The effective interest rate paid by the engineer can be calculated using the following formula:

effective_rate = total_cost / principal

effective_rate = $4,700 / $27,500

effective_rate = 0.1709 or 17.09%

Therefore, the effective interest rate paid by the engineer for the loan is 17.09%.

The demand schedule is not included in the question. Hence, the question cannot be answered directly. However, the steps to draw a demand curve from the accompanying demand schedule are given below.

Steps to draw a demand curve:

1. Identify the price and quantity demanded pairs from the demand schedule.
2. Plot the price on the vertical axis and the quantity demanded on the horizontal axis.
3. Mark the price-quantity pairs on the graph and connect them to form a smooth curve.

Now let's understand the types of elasticity of demand and how to find them:

Elastic demand: The demand is said to be elastic when a small change in price causes a larger change in the quantity demanded. The elasticity of demand is greater than 1.

Inelastic demand: The demand is said to be inelastic when a large change in price causes a small change in the quantity demanded. The elasticity of demand is less than 1.

Unit elastic demand: The demand is said to be unit elastic when a change in price causes an equal proportional change in quantity demanded. The elasticity of demand is equal to 1.

The mid-point method can be used to find the types of elasticity of demand. It is a formula that helps in calculating the elasticity of demand when the price and quantity demanded are given.

The mid-point method formula is given as follows:

Elasticity of demand = (Q2 - Q1) / [(Q2 + Q1) / 2] / (P2 - P1) / [(P2 + P1) / 2]

If the elasticity of demand is greater than 1, the demand is elastic. If the elasticity of demand is less than 1, the demand is inelastic. If the elasticity of demand is equal to 1, the demand is unit elastic.

Firms are interested in the type of elasticity of demand because it helps them determine the price and quantity demanded relationship. If the demand is elastic, they have to be careful while increasing the price because it might result in a decrease in revenue due to the decrease in quantity demanded. If the demand is inelastic, they can increase the price as the change in quantity demanded is not significant.

The change in Jayson's consumer surplus is $17.63 (nearest penny).

Given the inverse demand function for chain, measured in feet (can be irrational) p(q)=64/q2. The price per foot of chain fell from $6.25 to $4. The change in Jayson's consumer surplus is $ (Round to nearest penny. Do not include dollar sign in your answer).

So, we are to find the change in Jayson's consumer surplus.Given inverse demand function for chain: `p(q) = 64/q[tex]x^{2}[/tex]2`.Now, consumer surplus, `CS = ∫[0, q] (p(q) - a) dq`, where a = price per foot of chain, q = quantity of chain demanded.

Putting the given values of price per foot of chain: $6.25, $4 into the demand function we have `p( q) = 64/q[tex]x^{2}[/tex]2`.Consumer surplus before the change in the price of the chain: `CS1 = ∫[0, q] (64/q^2 - 6.25) dq`Consumer surplus after the change in the price of the chain: `CS2 = ∫[0, q] (64/q^2 - 4) dq`

Now, to find the change in Jayson's consumer surplus, we will subtract CS1 from CS2.`CS2 - CS1 = ∫[0, q] (64/q[tex]x^{2}[/tex]2 - 4) dq - ∫[0, q] (64/q[tex]x^{2}[/tex]2 - 6.25) dq`On simplification, we get:`CS2 - CS1 = (64 ln(q))/q|0,q - 4q|0,q`Since q > 0, we can substitute the value of q and solve the expression.`CS2 - CS1 = (64 ln(q))/q - 4q = 4(16/q - q)`

The demand function is p(q) = 64/q^2; therefore, p'(q) = -128/q[tex]x^{2}[/tex]3`The elasticity of demand `ε = p'(q) * q/p(q) = -128/q[tex]x^{2}[/tex]3 * q/(64/q[tex]x^{2}[/tex]2) = -2`Now, `Δa/a = -ε * Δp/p = -(-2) * (4 - 6.25)/6.25`Here, Δp = 4 - 6.25 = -2.25 and a = 6.25. Substituting these values, we get:Δa/a = -(-2) * (-2.25)/6.25 = 0.72.

Consumer surplus after the change in price: `CS2 = (16/2) (ln 2 + 1) = 16(ln 2 + 1)`Consumer surplus before the change in price: `CS1 = (16/2) (ln 1 + 1) = 8`Thus, the change in Jayson's consumer surplus is:`CS2 - CS1 = 16(ln 2 + 1) - 8 = 16 ln 2 + 8`.

The total surplus created in a perfectly competitive market is 5Q. The total surplus created by the monopolist is equal to the difference between the total revenue and total cost.

Total revenue is equal to the demand times the quantity, which in this case is (20-Q) * Q = 20Q - Q2. Total cost is equal to the marginal cost times the quantity, which is 15Q. Therefore, the total surplus created is 20Q - Q2 - 15Q = 5Q - Q2.

If the monopolist operated as if it were a perfectly competitive firm, the total surplus would be equal to the consumer surplus plus the producer surplus. In a perfectly competitive market, price is equal to marginal cost, so the price would be 15 in this case. The consumer surplus would be the area between the demand curve and the price (15), so it is equal to (20 - 15) * Q = 5Q. The producer surplus would be the area between the price (15) and the marginal cost (15), so it is equal to 0. Therefore, the total surplus created in a perfectly competitive market is 5Q.

The present value of the cash flows generated by the computer rental business is Php 230,048.26.

To determine whether the young graduate should invest in the computer rental business, we need to calculate the present value of the cash flows generated by the business and compare it with the initial investment cost of Php 200,000.

First, let's calculate the annual cash flow generated by one computer:

The total annual cash flow generated by 10 computers would be:

Total annual cash flow = Php 6,400 x 10 = Php 64,000

Now, we need to calculate the present value of the cash flows for the study period of 5 years, with a minimum attractive rate of return (MARR) of 15% per year.

Using the formula for present value of an annuity, we get:

Present Value = Cash Flow x (1 - (1 + r)^-n) / r

Where:

Cash Flow = Php 64,000 (annual cash flow)

r = 15% (MARR)

n = 5 (study period)

Substituting the values, we get:

Present Value = Php 64,000 x (1 - (1 + 0.15)^-5) / 0.15

Present Value = Php 230,048.26

Therefore, the present value of the cash flows generated by the computer rental business is Php 230,048.26.
