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 fabour 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 (desiss and cabinets). The following data are available for a typical quarter. Each product consumed 690 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.) 2. Redo the above using direct labour-hours as the allocation base. (Round "Cost per unit" answers to 2 decimal places
