Green Furniture (GF) manufactures a variety of furniture for household use and just two items for office use: desks and cabinets. The production process for desks and cabinets is similar, although machines must be retooled for each product. Both materials and labour costs are directly traceable to individual products; however, overhead is a common cost and allocated using direct labour-hours as the allocation base. GF's accountant is considering the use of activity-based costing (ABC) and has suggested evaluating the system by applying it to the two office use products (desks and cabinets). The following data are available for a typical quarter. Activity Cost Pool Parts receipts. Machining Assembly Quality control Direct materials: Direct labour Activity Base Number of parts Machine-hours Units produced Units tested Activity Rate $1.00 per part $11.00 per machine-hour $ 1.60 per unit $ 2.00 per unit Activity Usage Desks 1,700 parts 170 machine-hours i 850 units 85 units $ 4,250 $10,200 Cabinets 1,150 parts 260 machine-hours 1,150 units 1,050 units $ 2,300 $10,200 Each product consumed 510 direct labour-hours. " Required: 1. Determine the total manufacturing cost and cost per unit for each of the two product lines for the quarter, using activity-based costing to allocate overhead costs. (Round "Cost per unit" answers to 2 decimal places.) Desks Cabinets Total manufacturing cost. Cost per unit 2. Redo the above using direct labour-hours as the allocation base. (Round "Cost per unit" answers to 2 decimal places.) Total manufacturing cost Cost per unit Desks Cabinets
