Can someone please help me solve this problem? I am completely lost.

Problem 4-3A Shaker 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 2017 are as follows. Overhead Cost Pools Amount Purchasing Handling materials Production (cutting, milling, finishing) Setting up machines Inspecting Inventory control (raw materials and finished goods) Utilities Total budgeted overhead costs $75,000 82,800 221,000 101,250 114,000 141,120 360,000 $1,095,170 For the last 4 years, Shaker Stairs Co. has been charging overhead to products on the basis of machine hours. For the year 2017, 100,000 machine hours are budgeted. Jeremy Nolan, owner-manager of Shaker Stairs Co., recently directed his accountant, Bill Seagren, to implement the activity-based costing system that he has repeatedly proposed. At Jeremy Nolan's request, Bill and the production foreman identify the following cost drivers and their usage for the previously budgeted overhead cost pools. Activity Cost Pools Cost Drivers Purchasing Handling materials Production (cutting, milling, finishing) Setting up machines Inspecting Inventory control (raw materials and finished goods) Utilities Number of orders Number of moves Direct labor hours Number of setups Number of inspections Number of components Square feet occupied Expected Use of Cost Drivers 600 8,000 100,000 1,250 6,000 168,000 90,000 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. Direct materials $104,000 Direct labor Machine hours Direct labor hours Number of purchase orders Number of material moves Number of machine setups Number of inspections Number of components Number of square feet occupied $112,800 15,000 5,100 60 800 100 450 16,000 8,000 Compute the predetermined overhead rate using traditional costing with machine hours as the basis. (Round answer to 2 decimal places, e.g. 12.25.) $ Predetermined overhead rate per machine hour What is the manufacturing cost per stairway under traditional costing?
