Benoit company produces three products—a, b, and c. data concerning the three products follow (per unit): product a b c selling price $ 80.00 $ 62.00 $ 81.00 variable expenses: direct materials 24.00 18.00 9.00 other variable expenses 24.00 25.40 43.65 total variable expenses 48.00 43.40 52.65 contribution margin $ 32.00 $ 18.60 $ 28.35 contribution margin ratio 40 % 30 % 35 % the company estimates that it can sell 800 units of each product per month. the same raw material is used in each product. the material costs $3 per pound with a maximum of 5,000 pounds available each month. required: 1. calculate the contribution margin per pound of the constraining resource for each product. 2. which orders would you advise the company to accept first, those for a, b, or c? which orders second? third?

My answer is: Produce Product C first, then followed by Product A. to maximize contribution margin. Product B will not be produced since the maximum number of pounds has already been used in producing Products C and A.
