Use the information in Exercise 5-6A to complete the following requirements. Assume that before shifting to activity-based costing, Snowden Industries allocated all overhead costs based on direct labor hours. Direct labor data pertaining to the two decoders follow:

                                            Direct Labor Hours

Decoder P ...................................... 8,000

Decoder Q ..................................... 16,000

Total ............................................ 24,000

Required

a. Compute the amount of overhead cost allocated to each type of decoder when using direct labor hours as the allocation base.

b. Determine the cost per unit for overhead when using direct labor hours as the allocation base and when using ABC. Round your figures to two decimal points.

c. Explain why the per-unit overhead cost is lower for the high-volume product when using ABC.
