Keller Company makes two models of battery-operated boats, the Sandy Beach and the Rocky River. Basic production information follows:

	Sandy Beach			Rocky River
Direct materials cost per unit	$	19.60		$	27.30
Direct labor cost per unit		13.20			17.20
Sales price per unit		82.10			105.00
Expected production per month		1,250	units		950	units

Keller has monthly overhead of $12,203, which is divided into the following cost pools:

Setup costs	$	3,100
Quality control		5,487
Maintenance		3,616
Total	$	12,203

The company has also compiled the following information about the chosen cost drivers:

	Sandy Beach	Rocky River	Total
Number of setups	12	38	50
Number of inspections	170	295	465
Number of machine hours	1,600	1,600	3,200

Required: 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. (Do not round intermediate calculations and round your final answers to the nearest whole dollar amount.)

Total Overhead Cost

2. Calculate the production cost per unit for each of Kellers products under a traditional costing system. (Round your intermediate calculations and final answers to 2 decimal places.)

3. Calculate Kellers gross margin per unit for each product under the traditional costing system. (Round your intermediate calculations and final answers to 2 decimal places.)
