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: Total Pooled Cost Types of Costs Indirect labor wages, supplies, factory utilities, nachine Category Cost Driver Unit $ 653, 200 Machine hours maintenance Batch 806,100 Materials handling, inventory storage, labor for setups, packaging, labeling and shipping, scheduling Research and development Rent, general utilities, maintenance, facility depreciation, Square footage admin. salaries Number of production orders Product 211, 300 513,000 Time spent by research department Facility Additional data for each of the product lines follow: Total Connercial $ 35.70/unit $ 13.90/hour 6,000 19,000 290 14% Hone $ 24.10/unit $ 13.90/hour 12,300 49,000 2,200 19% Miniature $ 29.20/unit $ 17.20/hour 2,300 3,000 310 67% Direct materials cost Direct labor cost Number of labor hours Number of machine hours 20,600 71,000 2,880 100% 66,000 90, 00e Number of production orders Research and development time 13,000 16,000 12, e0e 21,e00 Number of units 41,000 53,000 Square footage 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 Commercial Home Miniature Combined total b Commercial Home Miniature Combined total
