The Electrotech Corporation manufactures two industrial-sized electrical devices: generators and alternators. Both of these products require wiring and testing during the assembly process. Each generator requires 2 hours of wiring and 1 hour of test- ing and can be sold for a $250 profit. Each alternator requires 3 hours of wiring and 2 hours of testing and can be sold for a $150 profit . There are 260 hours of wiring time and 140 hours of testing time available in the next production period and Elec- trotech wants to maximize profit. a. How much excess wiring and testing capacity exists in the optimal solution? b. What is the company's total profit if it has 10 additional hours of wiring capacity? c. By how much does the profit on alternators need to increase before their pro- duction is justified? d. Does the optimal solution change if the marginal profit on generators decreases by $50 and the marginal profit on alternators increases by $75?" e. Suppose the marginal profit on generators decreases by $25. What is the maxi- mum profit that can be earned on alternators without changing the optimal solution? 1. Suppose the amount of wiring required on alternators is reduced to 1.5 hours. Does this change the optimal solution? Why or why not? dtv
