The answer is 8 bags of popcorn and then $52.5
Step-by-step explanation:
In order to do this, you need to find the unit rate. In order to find the unit rate, divide 11.25 and 3. The answer should be 3.75. Using this number, divide 30 by 3.75 to get 8. 8 will be the number of popcorn bags sold. Then all you have to do is multiple 14 by 3.75 to get $52.50.

Solve the following algebraic equation. Show each step of the process.
6(x - 8) = 96
Answers
Answer:
x= 24
Step-by-step explanation:
Multiply each term in the parentheses. Not sure if this helps but I hope it does.
6(x−8)=96
(6)(x)+(6)(−8)=96(Distribute)
6x+−48=96
6x−48=96
Step 2: Add 48 to both sides.
6x−48+48=96+48
6x=144
Step 3: Divide both sides by 6.
6x

Answer:
6 Mechanical Pencils

A school has 400 students. They all come to school by bus, and each bus carries the same number of students. How many students might there be on each bus?
I put some counters into groups with the same number in each group. I can’t remember what I did, but I do remember that I had 12 counters. What might the groups have been?
Answers
Answer:
23 times 8 then divide the answer by two
(i looked it up and the answers are the same.)
Question 1 A. Do 23 times 2 times 2. This will give you the same answer as if you were to use 4.
Question 1 B. Use 10 times 2 plus the number in the ones place, then multiply them together.
Question 2. There would be an average of 40 student per bus, therefore, there will be 10 buses, and 40 students in each bus.
Question 3. You could put 12 counters in: 6 groups of 2, 2 groups of 6, 4 groups of 3, or 3 groups of 4. (I think there's more but that's all I can think of. Hope you got the memo)

Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across the domain.

Hope It Helps
The domain of the given function is [0,55] and the average rate of change is -1.45 so option (C) is correct.
What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
The domain is for the independent variable while the range is for the dependent variable.
The domain of a function is the set of input values that the function defines.
The function goes from x = 0 to x = 55 thus 0 ≤ x ≤ 55 will be the domain.
The average slope for (0,80) and (55,0)
⇒ (0 - 80)/(55 - 0) = -1.45
Hence "The domain of the given function is [0,55] and the average rate of change is -1.45".
