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.) 2.

Calculate Harbours gross margin per unit for each product under the traditional costing system. (Round your intermediate calculations and final answers to 2 decimal places.) 4. Select the appropriate cost driver for each cost pool and calculate the activity rates if Harbour wanted to implement an ABC system. 5. Assuming an ABC system, assign overhead costs to each product based on activity demands. 6. Calculate the production cost per unit for each of Harbours products in an ABC system. (Round your intermediate calculations and final answers to 2 decimal places.) 7. Calculate Harbours gross margin per unit for each product under an ABC system. (Round your intermediate calculations and final answers to 2 decimal places.) 8. Compare the gross margin of each product under the traditional system and ABC. (Round your answers to 2 decimal places.)
