Its budgeted manufacturing overhead costs for the year 2022 are as follows. Purchasing Overhead Cost Pools Handling materials Amount $ 45,000 50,000 Production (cutting, milling, finishing) 130,000 Setting up machines 85,000 Inspecting 60,000 Inventory control (raw materials and finished 80,000 goods) Utilities Total budget overhead costs 100,000 $550,000 For the past four years, Prime Furniture has been charging overhead to products on the basis of materials cost. For the year 2022, materials costs of $500,000 were budgeted. Wei Huang, owner-manager of Prime Furniture, recently directed her accountant, Tom Turkel, to implement the activity-based costing system that he has repeatedly proposed. At Wei Huang's request, Tom and the production manager identify the following cost drivers and their usage for the previously budgeted overhead cost pools.
