Keller Company makes two models of battery-operated boats, the Sandy Beach and the Rocky Rivet. Basic production information follows: The company also has compiled the following information about the chosen cost drivers: 1. Suppose Keller uses a traditional costing system with machine hours as the cost driver. Determine the amount of overhead assigned to each product line. 2. Calculate the production cost per unit for each of Keller's products under a traditional costing system. 3. Calculate Keller's gross margin per unit for each product under the traditional costing system. 4. Select the appropriate cost diver for each activity pool and calculate the activity rates if Keller wan'ed to implement an ABC system. 5. Assuming an ABC system, assign overheod costs to each product based on activity demands. 6. Calculate the production cost per unit for each of Keller's products with an ABC system. 7. Calculate Keller's gross margin per unit for each product under an ABC system. 8. Compare the gross margl of each product under the traditional system and ABC.
