The company's estimated total manufacturing overhead for the year is $2,656,000 and the
company's estimated total direct labor-hours for the year is 64,000.
The company is considering using a variation of activity-based costing to determine its unit
product costs for external reports. Data for this proposed activity-based costing system appear

Required:
a. Compute the predetermined overhead rate under the current method, and determine the unit
product cost of each product for the current year.
b. The company is considering using an activity-based costing system to compute unit product
costs for external financial reports instead of its traditional system based on direct labor-hours.
The activity-based costing system would use three activity cost pools. Data relating to these
activities for the current period are given below:
