Question

For many years, Thomson Company manufactured a single product called LEC 40. Then three years ago, the company automated a portion of its plant and at the same time introduced a second product called LEC 90 that has become increasingly popular. The LEC 90 is a more complex product, requiring 0.60 hours of direct labor time per unit to manufacture and extensive machining in the automated portion of the plant. The LEC 40 requires only 0.20 hours of direct labor time per unit and only a small amount of machining. Manufacturing overhead costs are currently assigned to products on the basis of direct labor-hours.

Despite the growing popularity of the company’s new LEC 90, profits have been declining steadily. Management is beginning to believe that there may be a problem with the company’s costing system. Direct material and direct labor costs per unit are as follows:

	LEC 40		LEC 90
Direct materials	$	28.00	$	44.00
Direct labor (0.20 hours and 0.60 hours @ $10.00 per hour)	$	2.00	$	6.00

Management estimates that the company will incur $856,000 in manufacturing overhead costs during the current year and 80,000 units of the LEC 40 and 40,000 units of the LEC 90 will be produced and sold.

Required:

1-a. Compute the predetermined overhead rate assuming that the company continues to apply manufacturing overhead cost on the basis of direct labor-hours.

1-b. Using this rate and other data from the problem, determine the unit product cost of each product.

1-a.

Compute the predetermined overhead rate assuming that the company continues to apply manufacturing overhead cost on the basis of direct labor-hours. (Round your answer to 2 decimal places.)

	Predetermined overhead rate per DLH

1-b.

Using this rate and other data from the problem, determine the unit product cost of each product. (Do not round intermediate calculations. Round your final answers to 2 decimal places.)

	LEC 40 LEC 90 Unit product cost

Answer 1

(1a) Compute the predetermined overhead rate assuming that the company continues to apply manufacturing overhead cost on the basis of direct labor-hours. (Round your answer to 2 decimal places.)

	Predetermined overhead rate $21.40 per DLH

Manufacturing OH/Total Direct Labor Hours

Manufacturing OH = $856000

Direct Labor Hours = (80000 * 0.20) + (40000 * 0.60) = 40000 Hours

Predetermined overhead rate = $856000/40000 hours = $21.40 per DLH

1-b.

Using this rate and other data from the problem, determine the unit product cost of each product. (Do not round intermediate calculations. Round your final answers to 2 decimal places.)

	LEC 40 LEC 90 Unit product cost $34.28 $62.84

	LEC 40	LEC 90
Direct materials	$28	$44
Direct labor	$2	$6
Manufacturing Overhead	($21.40 * 0.2) =$4.28	($21.40 * 0.6) =$12.84
Unit product cost	$34.28	$62.84
