I need help answering this question.

Stuart Electronics produces video games in three market categories: commercial, home, and miniature. Stuart 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 Total Pooled Cost Types of Costs Cost Driver Unit $638, 400 Indirect labor wages, supplies, factory utilities, Machine hours machine maintenance Batch 575, 800 Materials handling, inventory storage, labor for Number of production orders setups , packaging, labeling and shipping, scheduling Product 211, 400 Research and development Time spent by research department Facility 514, 800 Rent, general utilities, maintenance, facility Square footage depreciation, admin. salaries Additional data for each of the product lines follow: Commercial Home Miniature Total Direct materials cost $ 35. 70/unit $ 24.30/unit $ 30 . 40/unit Direct labor cost $ 15.20/hour $ 15. 20/hour $ 17. 80/hour Number of labor hours 5, 300 12, 500 2,000 19 , 800 Number of machine hours 11, 000 49,000 16,000 76,000 Number of production orders 260 1,900 940 3, 100 Research and development time 13% 228 65% 100% Number of units 13,000 45,000 12,000 70,000 Square footage 20,000 52,000 27,000 99,000 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.{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.)
