Zachary Electronics produces video games in three market categories: commercial, home, and miniature. Zachary has traditionally allocated overhead costs to the three products using the companywide allocation base of direct labor hours. The company recently implemented an ABC system when it installed computer-controlled assembly stations that rendered the traditional costing system ineffective. In implementing the ABC system, the company identified the following activity cost pools and cost drivers: Category Unit Total Pooled Cost $ 779,000 Cost Driver Machine hours Batch 486,400 Number of production orders Types of costs Indirect labor wages, supplies, factory utilities, machine maintenance Materials handling, inventory storage, labor for setups, packaging, labeling and shipping, scheduling Research and development Rent, general utilities, maintenance, facility depreciation, admin. salaries Product Facility 210,800 531,000 Time spent by research department Square footage Additional data for each of the product lines follow: Total Direct materials cost Direct labor cost Number of labor hours Number of machine hours Number of production orders Research and development time Number of units Square footage Commercial $ 35.80/unit $ 15.20/hour 6,300 14,000 300 12% 16,000 19,000 Home $ 24.10/unit $ 15.20/hour 11,500 44,000 2,200 24% 41,000 45,000 Miniature $ 29.10/unit $ 17.80/hour 1,500 24,000 400 64% 15,000 26,000 19,300 82,000 2,900 100% 72,000 90,000 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. Also determine the combined cost of all three product lines. b. Determine the total cost and cost per unit for each product line, assuming that an ABC system is used to allocate overhead costs. Determine the combined cost of all three product lines. (For all requirements, round intermediate calculations for allocation rates to 2 decimal places and all other calculations to the nearest whole dollar. Round "Cost per Unit" to 2 decimal places. Round your answers for "Total Cost" to the nearest whole dollar amount.) Type of Product Total Cost Cost per Unit a. Commercial Home Miniature Combined total $ 0 b.
