1. Product Costs and Product Profitability Reports, using a Single Plantwide Factory Overhead Rate

   Isaac Engines Inc. produces three productspistons, valves, and camsfor the heavy equipment industry. Isaac Engines has a very simple production process and product line and uses a single plantwide factory overhead rate to allocate overhead to the three products. The factory overhead rate is based on direct labor hours. Information about the three products for 20Y2 is as follows:

   	Budgeted Volume (Units)		Direct Labor Hours Per Unit		Price Per Unit		Direct Materials Per Unit
   Pistons	6,000		0.30		$40		$ 9
   Valves	13,000		0.50		21		5
   Cams	1,000		0.10		55		20

   The estimated direct labor rate is $20 per direct labor hour. Beginning and ending inventories are negligible and are, thus, assumed to be zero. The budgeted factory overhead for Isaac Engines is $235,200.

   If required, round all per unit answers to the nearest cent.

   a. Determine the plantwide factory overhead rate. $ per dlh

   b. Determine the factory overhead and direct labor cost per unit for each product.

   	Direct Labor Hours Per Unit	Factory Overhead Cost Per Unit	Direct Labor Cost Per Unit
   Pistons	dlh	$	$
   Valves	dlh	$	$
   Cams	dlh	$	$

   a. First calculate: Volume x Direct Labor Hours per Unit = Direct Labor Hours per Product. Add all product hours for total direct labor hours. Next: Total Budgeted Factory Overhead Total Budgeted Plantwide Allocation Base = Single Plantwide Factory Overhead Rate

   b. Calculate: Factory Overhead Cost per Unit = Rate from Req. (a) x Direct Labor Hours per Unit Direct Labor Cost per Unit = Direct Labor Rate x Direct Labor Hours per Unit

   c. Use the information provided to construct a budgeted gross profit report by product line for the year ended December 31, 20Y2. Include the gross profit as a percent of sales in the last line of your report, rounded to one decimal place.
