2 Carco manufactures cars and trucks. Each car contributes $300 to profit, and each truck contributes $400.

The resources required to manufacture a car and a truck are shown in Table 5. Each day, Carco can rent up to 98 Type 1 machines at a cost of $50 per machine. The company has 73 Type 2 machines and 260 tons of steel available.

Marketing considerations dictate that at least 88 cars and at

least 26 trucks be produced. Let x1 = number of cars produced daily; x2 = number of trucks produced daily; and m1 = Type 1 machines rented daily.
To maximize profit, Carco should solve the LP in Figure 7. Use the LINDO output to answer the following questions:
a If each car contributed $310 to profit, what would be the new optimal solution to the problem?

b If Carco were required to produce at least 86 cars, what would Carco’s profit become?
