. Computer Accessories' controller, Ms. Vella Rose, recently attended a conference at which activity-based costing systems were discussed. She became convinced that such a system would help Computer Accessories' management to understand its product costs better. She got top management's approval to design an activity-based costing system, and an ABC project team was formed. In stage one of the ABC project, each of the overhead items listed in the overhead budget was placed into its own activity cost pool. Then a cost driver was identified for each activity cost pool. Finally, the ABC project team compiled data showing the percentage of each cost driver that was consumed by each of Computer Accessories' product lines. These data are summarized as follows: Activity Cost Pool Cost Driver Motherboard Power Supply CPU Machine setup Number of setups 20% 30% 50% Machinery Machine hours 25% 50% 25% Inspection Number of inspections 15% 45% 40% Material handling Raw-material costs 25% 69% 6% Engineering Number of change orders 35% 10% 55% a. Calculate unit product costs and the target prices for the three products using an activity-based costing system. (Round to the nearest cent.) Show all necessary workings
