Problem 4 (5 points): Wright on the Beach produces three types of beach chairs that all require processing on the same machines. There are only 27,000 machine hours available in each year. Production information for each product is: Required: JW DW EW Sales Price Per Unit $ 20 $ 40 $ 33 Variable Cost Per Unit $ 8 $ 27 $ 16 Labor Hours Required per Unit 2.5 4.0 4.5 a. Assuming there is no limit on resources, which is the most profitable product? Explain DW because 40/4=$10 for JW H's 70/2.5=18 and 4 3/45-1 b. Given there is a constraint described in this problem, what is the contribution margin for the constrained resource for each of the three products? c. Which product would be the most profitable use of the constrained resource?
