Consider an economy with 100 pieces of apple (A) and 150 pieces of banana (B) that must be completely distributed to individuals 1 and 2. The utility function of the two individuals, U1 & U2, is given by U1 (A1,B1) = 2A2 + B2 & U2 (A2,B2) = 2A2B2, respectively.

(4 pts) hokie manufacturing is planning to buy a new printing machine. they are considering two different machines manufactured by two different companies. the appropriate discount rate is 20%. variables to consider for each project are as follows machine a - $50,000 cost; functional life of 9 years; expected cash flow of $20,000 per year machine b - $75,000 cost; functional life of 7 years; expected cash flow of $30,000 per year; plus, a salvage value of $10,000 for the machine in 7 years. calculate npv and irr for each machine. clue for the machine b calculation. salvage value should be considered as a future payment that needs to be discounted back. in your opinion, which machine should hokie manufacturing select? salvage value is based on an assumption that machine b will have a value of $10,000 seven years from now. what variables could impact that assumption?
