Required:
a. Determine the total cost and cost per unit for each product line, assuming that overhead costs are allocated to each product line using direct labor hours as a companywide allocation base. Show your computations.
b. Determine the total cost and cost per unit for each product line, assuming that an ABC system is used to allocate overhead costs. Show your computations.
c. Given that the combined total cost is the same using either allocation method, why is an ABC system with many different allocation rates usually better than a traditional system with a single companywide overhead rate?
