Crane Stairs Co. designs and builds factory-made premium wooden stairways for homes. The manufactured stairway components (spindles, risers, hangers, hand rails) permit installation of stairways of varying lengths and widths. All are of white oak wood. Budgeted manufacturing overhead costs for the year 2022 are as follows. Steve Hannon, sales manager, has received an order for 250 stairways from Community Builders, Inc., a large housing development contractor. At Steve's request, Bill prepares cost estimates for producing components for 250 stairways so Steve can submit a contract price per stairway to Community Builders. He accumulates the following data for the production of 250 stairways. What is the manufacturing cost per stairway under traditional costing? (Round answer to 2 decimal places, e.g. 12.25.)

What is the manufacturing cost per stairway under the proposed activity-based costing? (Round answer to 2 decimal places, e.g. 12.25.) Total manufacturing cost per stairway Calculate total overhead assigned under ABC. Total overhead assigned For the last 4 years, Crane Stairs Co. has been charging overhead to products on the basis of machine hours. For the year 2022 , 100,000 machine hours are budgeted.
