Shady Fabrication Group (SFG) manufactures components for manufacturing equipment at several facilities. The company produces two, related, parts at its Park River Plant, the models SF-08 and SF-48. The differences in the models are the quality of the materials and the precision to which they are produced. The SF-48 model is used in applications where the precision is critical and thus requires greater oversight in the production process. Although sales remain reasonably strong, managers at SFG have noticed that the company is meeting more resistance to the pricing for SF-08, although there seems to be little need for negotiation on the price of the SF-48 model. As a result, the marketing manager at SFG has asked the financial staff to review the costs of the two products to understand better what might be happening in the market. Manufacturing overhead is currently assigned to products based on their direct labor costs. For the most recent month manufacturing overhead was $180,000. During that time, the company produced 8,000 units of Model SF-08 and 2,000 units of Model SF-48. The direct costs of production were as follows: Direct materials Direct labor SF-08 $ 160,000 120,000 SF-48 $ 90,000 80,000 Total $ 250,000 200,000 Management determined that overhead costs are caused by three cost drivers. These drivers and their costs for last month were as follows:
