Campbell Electronics produces video games in three market categories: commercial, home, and miniature. Campbell 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 $782,000 Cost Driver Machine hours Batch 343,200 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 Number of production orders Product Facility 211,100 516,200 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 $ 15.10/hour 6,600 17,000 210 13% 14,000 18,000 Home $ 23.70/unit $ 15.10/hour 11,500 44,000 2,100 17% 43,000 55,000 Miniature $ 30.60/unit $ 17.40/hour 1,400 24,000 390 70% 13,000 16,000 19,500 85,000 2,700 100% 70,000 89,000 Required a.
