Addison Company Has Two Products: a and B

Addison Company has two products: A and B. Annual production and sales are 800 units of Product A and 700 units of Product B. The company has traditionally used direct labour-hours as the basis for applying all manufacturing overhead to products. Product A requires 0.2 direct labour hours per unit and Product B requires 0.6 direct labour hours per unit. The total estimated overhead for next period is $71,286.
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 factory overhead activity cost pools—Activity 1, Activity 2, and General Factory—with estimated overhead costs and expected activity as follows:

(Note: The General Factory activity cost pool's costs are allocated on the basis of direct labour hours.)
-(Appendix 5B) The overhead cost per unit of Product B under the activity-based costing system is closest to:

A) $73.74
B) $56.62
C) $22.38
D) $47.52
