1. Kinney Industries has recently switched its method of applying manufacturing overhead from a single predetermined overhead rate based on direct labor hours to activity-based costing (ABC). Assume that the direct labor rate is $18.00 per hour and that there were no beginning inventories. The following cost drivers and rates have been developed for allocating manufacturing overhead costs:
Activity Cost Driver Rate
Material handling Number of parts used $2.00 per part
Assembly and inspection Number of direct labor hours $25.00 per DLH
Testing Number of units tested $5.00 per unit
The following production, costs, and activities occurred during the month of August:
Units Produced Direct Material Cost Number of Parts Used Direct Labor Hours
6,400 $208,600 142,000 26,480
Required:
A) Calculate the total manufacturing cost and the cost per unit for the month of August.
B) Assume instead that Kinney Industries applies manufacturing overhead on the basis of $40.00 per
direct labor hours (rather than the ABC method). Calculate the total manufacturing overhead cost applied for the month of August.
