Textbook Problem

During the week of June 12, Harrison Manufacturing produced and shipped 15,000 units of its aluminum wheels: 3,000 units of Model A and 12,000 units of Model B. The following costs were incurred:

Required:

1. 1. Assume initially that the value-stream costs and total units shipped apply only to one model (a single-product value stream). Calculate the unit cost, and comment on its accuracy.
2. 2. Calculate the unit cost for Models A and B, and comment on its accuracy. Explain the rationale for using units shipped instead of units produced in the calculation.
3. 3. What if Model A is responsible for 40 percent of the materials cost? Show how the unit cost would be adjusted for this condition.
