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 0.80 hours of direct labor time per unit to manufacture and extensive machining in the automated portion of the plant. The LEC 40 requires only 0.40 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 companys new LEC 90, profits have been declining steadily. Management is beginning to believe that there may be a problem with the companys costing system. Direct material and direct labor costs per unit are as follows:

	LEC 40		LEC 90
Direct materials	$	24.00	$	44.00
Direct labor (0.40 hours and 0.80 hours @ $10.00 per hour)	$	4.00	$	8.00

Management estimates that the company will incur $744,000 in manufacturing overhead costs during the current year and 60,000 units of the LEC 40 and 20,000 units of the LEC 90 will be produced and sold.

3. Using the activity rates you computed in part (2), do the following:

part two rates:

ACTIVITY RATE
Activity costs pool	Activity rate
Maintaining parts inventory	$120 per part type
Processing purchase orders	$60 per purchase order
Quality control	$20 per test run
Machine-related	$76 per machine hour

Calculation of actvity rate
Activity cost pool	Activity Measure	Estimated overhead cost (a)	Expected activity (b)	Activity rate (c=a/b)
		$		$
Maintaining parts inventory	Number of part types	126000	1050	$120 per part type
Processing purchase orders	Number of purchase orders	120000	2000	$60 per purchase order
Quality control	Number of tests run	42000	2100	$20 per test run
Machine-related	Machine-hours	456000	6000	$76 per machine hour
	Total	744000

Activity Cost Pool	Activity Measure	Estimated Overhead Cost
Maintaining parts inventory	Number of part types	$	126,000
Processing purchase orders	Number of purchase orders		120,000
Quality control	Number of tests run		42,000
Machine-related	Machine-hours		456,000
		$	744,000

	Expected Activity
Activity Measure	LEC 40	LEC 90	Total
Number of part types	400	650	1,050
Number of purchase orders	1,400	600	2,000
Number of tests run	700	1,400	2,100
Machine-hours	4,000	2,000	6,000

a. Determine the per unit amount of manufacturing overhead cost that would be assigned to each product using the activity-based costing system.

b. Compute the unit product cost of each product.
