b) Acklin Company has two products: A and B. The annual production and sales of Product A is 600 units and of Product B is 900 units. The company has traditionally used direct labor-hours as the basis for applying all manufacturing overhead to products. Product A requires 0.5 direct labor-hours per unit and Product B requires 0.3 direct labor-hours per unit. The total estimated overhead for next period is $63,322. 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: Estimated Overhead Activity Cost Pool Costs Expected Activity Product A Product B Total Activity 1 $18,900 700 200 900 Activity 2 $15,631 1,000 100 1,100 General Factory $28,791 300 270 570 Total $63,322 (Note: The General Factory activity cost pool's costs are allocated on the basis of direct labor-hours.) Required: 01. The predetermined overhead rate under the traditional costing system is closest to: 02. The overhead cost per unit of Product A under the traditional costing system is closest to: 03. The predetermined overhead rate (i.e., activity rate) for Activity 1 under the activity-based costing system is closest to: 04. The overhead cost per unit of Product A under the activity-based costing system is closest to:
