Company ABC has a production line that produces two products, A and B. The company uses a traditional costing system, allocating overhead costs based on direct labor hours. The following information is available for the month of January:

• Product A: 1,500 units produced, 4,000 direct labor hours, $5,000 of direct materials, and $6,000 of manufacturing overhead allocated
• Product B: 2,500 units produced, 3,000 direct labor hours, $7,500 of direct materials, and $7,000 of manufacturing overhead allocated
• Total manufacturing overhead incurred for the month is $20,000

The company is considering switching to an activity-based costing system to allocate overhead costs. The company identified three activities that drive overhead costs: machine setup, material handling, and quality control. The following information is available for the month of January:

• Machine setup activity: 50 setups performed, $7,500 of costs incurred
• Material handling activity: 10,000 pounds of materials handled, $4,000 of costs incurred
• Quality control activity: 100 inspections performed, $8,500 of costs incurred
