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 |
$ |
25.00 |

44.00 |
Direct labor (0.20 hours and 0.60 hours @ $20.00 per hour) |
$ |
4.00 |
$ |
12.00 |
|
Management estimates that the company will incur $1,024,000 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.
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.)

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.)

Management is considering using activity-based costing to assign
manufacturing overhead cost to products. The activity-based costing
system would have the following four activity cost pools:
