Activity-Based Costing Steampunk Corporation has the following predicted indirect costs and cost drivers for 2019 for the given activity cost pools: Finishing Department Department Fabrication Cost Driver $ 30,000 15,000 Machine hours Maintenance Materials handling 22,500 Material moves 45,000 Machine 7,500 Machine setups 105,000 Inspections 37,500 Inspection hours $180,000 $82,500 Total The following activity predictions were also made for the year: Finishing Fabrication Department Department Machine hours 5,000 2,500 Material moves 1,500 750 Machine setups 350 25 Inspection hours 500 It is assumed that the cost per unit of activity for a given activity does not vary between departments. Steampunk's president, Abner Punk, is trying to evaluate the company's product mix strategy regarding two of its product models, SW100 and SG150. The company has been using a company wide overhead rate based on machine hours but is considering switching to either department rates of activity-based rate. The production manager has provided the following data for the production of a batch of 100 units for each of these models: SW100 SG150 $ 10,000 $ 15,000 Direct materials cost $ 4,000 Direct labor cost $ 3,000 Machine hours (Fabrication) 250 350 Machine hours (Finishing) 100 50 Materials moves 20 40 Machine setups 10 Inspection hours 15 30 a. Determine the cost of one unit each of SW100 and SG150, assuming a company-wide overhead rate is used based on total machine hours. Round rate to two decimal places. a.
