Bernacke Corp. is instituting an activity-based costing project in its  tenperson purchasing department. Annual departmental overhead costs are  $731,250. Because finding the best supplier takes the majority of effort  in the department, most of the costs are allocated to this activity  area. Many purchase orders are received in a single shipment.
