5-78. The controller for Wofford Machining has established the following overhead cost pools and cost drivers: Overhead Cost Pool Machine setups Material handling Quality control inspection Other overhead costs Total Budgeted Overhead Cost $240,000 90,000 48,000 160.000 $538.000 Cost Driver Number of setups Units of raw material Number of inspections Machine hours 200 setups Overhead Cost Pool Machine setups Material handling Quality control Other overhead Budgeted Level for Cost Driver Pool Rate $1,200 per setup 60,000 units $1.50 per unit 1,200 inspections $40 per inspection 20,000 machine hours $8 per machine hour Order no. 715 has the following production requirements: I Machine setups: 7 Raw material: 11,200 units Inspections: 16 Machine hours: 850 Required: A. Compute the total overhead that should be assigned to order no. 715 by using activity-based costing. B. Suppose that Wofford were to use a single, predetermined overhead rate based on machine hours. Compute the rate per hour and the total overhead assigned to order no. 715. C. Discuss the merits of an activity-based costing system in comparison with a traditional costing system
