The company’s simple (traditional) costing system uses a single indirect-cost pool and allocates costs to the two lamps on the basis of direct manufacturing labour-hours. Under this tradition system, determine total product cost per unit of each of the company's two products. (10 marks)
The company’s ABC system uses two indirect-cost pools. One cost pool is for set up costs and the other for quality control. Zany Brainy allocates set up costs to the two lamps based on setup labour-hours and quality control costs based on direct manufacturing labour-hours. Under ABC system, determine total product cost per unit of each of the company's two products. (25 marks)
