4. (Chapter 4) The Oakland plant has two categories of overhead: maintenance and inspection. Costs expected for these categories for the coming year are as follows:

Maintenance \$240,000
Inspection 500,000

The plant currently applies overhead using direct labor hours and expected capacity of 100,000 direct labor hours. The following data has been assembled for use in developing a bid for a proposed job. Bid prices are calculated as full manufacturing cost plus 20 percent markup.

Direct materials \$2,800
Direct labor \$7,500
Machine hours 900
Number of inspections 8
Direct labor hours 1,100

Total expected machine hours for all jobs during the year is 60,000, and the total expected number of inspections is 4,000.

Required:

a. Compute the total cost of the potential job using direct labor hours to assign overhead.

Also determine the bid price for the potential job.

b. Compute the total cost of the job using activity-based costing and the appropriate cost drivers.

Also determine the bid price if activity-based costing is used.

During the year Dewey Company used 37,000 direct labor hours.

At the end of the year, Dewey Company records revealed the following information:

Raw materials inventory \$ 35,000
Work-in-process inventory 60,000
Finished goods inventory 105,000
Cost of goods sold 400,000

Required:

a. Calculate the predetermined overhead rate for the year.

b. Determine the amount of overhead applied during the year.

c. Determine the amount of underapplied or overapplied manufacturing overhead for the year.

Conversion (10,000 x 40%) 4,000
Equivalent units of output 130,000 124,000

Costs assigned to beginning work in process:

Materials: \$68,000
Conversion: \$33,000

Manufacturing costs incurred during the month:

Materials: \$75,000
Conversion: \$60,000

Required:

a. Compute the unit cost for January using the weighted average method.

b. Determine the cost of goods transferred out.

c. Determine the cost of ending work in process.
