PA4-3 (Algo) Selecting Cost Drivers, Assigning Costs Using Activity Rates (LO 4-1, 4-3, 4-4, 4-6 ] Harbour Company makes two models of electronic tablets, the Home and the Work. Basic production information follows: Home Work Direct materials $ 40 $ 67 cost per unit Direct labor cost 16 38 per unit Sales price per 363 573 unit Expected production 770 units 400 units per month Harbour has monthly overhead of $154,370, which is divided into the following cost pools: Setup costs $ 71,610 Quality 55,760 control Maintenance 27,000 Total $154,370 The company has also compiled the following information about the chosen cost drivers: Home Work Total 41 52 93 Number of setups Number of inspections Number of machine hours 300 380 680 1,400 1,300 2,700 Required: 1. Suppose Harbour uses a traditional costing system with machine hours as the cost driver. Determine the amount of overhead assigned to each product line. (Do not round intermediate calculations and round your final answers to the nearest whole dollar amount.) Overhead Assigned 80,038 74,321 $ Home Model: Work Model: Total Overhead Cost $ $ 154,359 2. Calculate the production cost per unit for each of Harbour's products under a traditional costing system. (Round your intermediate calculations and final answers to 2 decimal places.) Home Work Unit Cost 3. Calculate Harbour's gross margin per unit for each product under the traditional costing system. (Round your intermediate calculations and final answers to 2 decimal places.) Home Work Gross Margin 4. Select the appropriate cost driver for each cost pool and calculate the activity rates if Harbour wanted to implement an ABC system. Setup Costs Quality Control Maintenance 5. Assuming an ABC system, assign overhead costs to each product based on activity demands.
