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 $39,000 Supervisory expense $11,500 Distribution of Resource Consumption Across Activity Cost Pools: Activity Cost Pools Machining Order Filling Other Equipment depreciation 0.50 0.30 0.20 Supervisory expense 0.50 0.20 0.30 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: MHs (Machining) Orders (Order Filling) Product I3 5,540 138 Product U8 23,900 940 Total 29,440 1,078 Finally, sales and direct cost data are combined with Machining and Order Filling costs to determine product margins. Sales and Direct Cost Data: Product I3 Product U8 Sales (total) $61,700 $69,300 Direct materials (total) $31,700 $22,600 Direct labor (total) $20,300 $31,400 What is the product margin for Product I3 under activity-based costing? (Round your intermediate calculations to 2 decimal places and final answer to the nearest dollar amount.)
