Adelberg Corporation makes two products: Product A and Product B. Annual production and sales are 500 units of Product A and 1,000 units of Product B. The company has traditionally used direct labor-hours as the basis for applying all manufacturing overhead to products. Product A requires 0.4 direct labor-hours per unit and Product B requires 0.2 direct labor-hours per unit. The total estimated overhead for next period is $68,756. The company is considering switching to an activity-based costing system for the purpose of computing unit product costs for external reports. The new activity-based costing system would have three overhead activity cost pools-Activity 1, Activity 2, and General Factory-with estimated overhead costs and expected activity as follows: Activity Cost Pool Activity 1 Activity 2 General Factory Total Estimated Overhead Costs Expected Activity Product At Product B Total $ 31,031 1,000 300 1,300 22,249 1,600 1,900 15,476 200 200 400 $ 68,756 (Note: The General Factory activity cost pool's costs are allocated on the basis of direct labor-hours.) The predetermined overhead rate (e, activity rate) for Activity 2 under the activity-based costing system is closest to:
