The next two questions are based on the following case: A manufacturer of hot tubs makes two kinds of hot tubs - Wishy and Washy. Wishy requires 7 hours of labor and Washy requires 8 hours. Wishy needs 50 feet of tubing and Washy needs 40 feet. The manufacturer expects to have 1500 labor hours and 9000 feet of tubing available. A single hot tub of type Wishy requires 2 pumps whereas type Washy requires 3 pumps. He has 500 pumps at his disposal. He expects to make a profit of $70 on each type of hot tub Wishy he sells and $50 on Washy. Let X= the number of Wishy bathtubs and Y= the number of Washy bathtubs manufactured. 5. The Objective Function for the LP problem is: a. Max 50 X+70Y b. Min 70X+50Y c. Max 70X*50Y d. Max 70X + 50Y 2 6. Which constraint(s) represent(s) the restriction on the amount of labor? a. 7X+8Y= 1500 b. 50X+40Y 9000 c. 14X+16Y 4000 d. 7X+8Y 1500 e. a and d both work.
