Walnut Systems produces two different products, Product A, which sells for $137 per unit, and Product B, which sells for $205 per unit, using three different activities: Design, which uses Engineering Hours as an activity driver; Machining, which uses machine hours as an activity driver; and Inspection, which uses number of batches as an activity driver. The cost of each activity and usage of the activity drivers are as follows: Usage by CostProduct A Usage by Product B 211 $607,750 1,080 $159,456 317 Design (Engineering Hours) Machining (Machine Hours) Inspection (Batches) 3,170 $ 28,800 18 Walnut manufactures 10,200 units of Product A and 6,800 units of Product B per month. Each unit of Product A uses $47 of direct materials and $13 of direct labor, while each unit of Product B uses $67 of direct materials and $29 of direct labor Required: a.
