Brisky Corporation uses activity-based costing to compute product margins. In the first stage, the activity-based costing system allocates two overhead accounts-equipment depreciation and supervisory expense-to three activity cost pools-Machining, Order Filling, and Other-based on resource consumption. Data to perform these allocations appear below: Overhead costs: Equipment depreciation $30,000 Supervisory expense $14,800 Distribution of Resource Consumption Across Activity Cost Pools: Activity Cost Pools Equipment depreciation 0.50 Machining Order Filling 0.40 Other 0.10 Supervisory expense 0.50 0.30 0.20 In the second stage, Machining costs are assigned to products using machine-hours (MHs) and Order Filling costs are assigned to products using the number of orders. The costs in the Other activity cost pool are not assigned to products. Activity: Orders (Order MHs (Machining) Filling) Product 13 5,530 161 Product U8 17,000 964 Total 22,530 1,125 Finally, sales and direct cost data are combined with Machining and Order Filling costs to determine product margins. Sales and Direct Cost Data: Product 13 Product U8 Sales (total) $69,700 $65,700 Direct materials (total) Direct labor (total) $31,100 $23,900 $22,400 $29,500 What is the product margin for Product 13 under activity-based costing? (Round your intermediate calculations to 2 decimal places and final answer to the nearest dollar amount.)
