Instructions:

a. Compute the predetermined overhead rate using traditional costing with machine hours as the basis. (Round answer to 2 decimal places, e.g. 10.50.)

b. What is the manufacturing cost per stairway under traditional costing? (Round answer to 2 decimal places, e.g. 10.50. Use the rounded amount from the previous question when calculating the answer for this question.)

c. What is the manufacturing cost per stairway under the proposed activity-based costing? (Prepare all of the necessary schedules. Round your computations for activity-based overhead rates and final answer to 2 decimal places, e.g. 10.50.)

d. Which of the two costing systems is prefereable in pricing decisions and why?
