Brickley Chains produces five different styles of silver chains, A, B, C, D, and E, in a highly auto-mated batch machining process. The following table summarizes the production and cost data for the five products.

Annual overhead is $ 80,000.

Required:
a. Compute the unit cost of each chain, A€“ E, using absorption costing. Overhead is assigned to individual products using direct laborcost.
b. Upon further analysis, you discover that the annual overhead of $ 80,000 consists entirely of the highly automated machining process. Each chain type is produced in batches with chains of the same type. Each batch requires the same amount of machine time. That is, producing a batch of 100 style A chains requires the same amount of machine time as a batch of 25 style E chains. The following table summarizes the batch size for each type of chain:

Product Batch Size
A.......... 100
B.......... 100
C.......... 50
D.......... 40
E .......... 25

Compute the unit cost of each chain, A€“ E, using activity- based costing.
c. Prepare a table comparing the activity- based cost and absorption cost of each product. Discuss why the product costs differ between the two costingmethods.
