Direct labor           28,000

Overhead applied 21,000

Total                   $65,000

4. Under- or overapplication of Manufacturing Overhead:

Actual overhead expense = $66,000

Applied overhead costs =      58,500

Underapplied by                     $7,500

Explanation:

a) We used journal entries to record the transactions for the jobs as they occurred during the month.  The entries showed which account was to be debited and which was to be credited, as every transaction affects the two sides of the accounting equation.  One account gave value and the other account received the value.  It is from the journal entries that the postings to the ledger accounts would be carried out.

b) In Watson Manufacturing Company's job costing system, each completed job is transferred out to the finished goods inventory account for sale.

c) Sometimes, the manufacturing overhead is underapplied or overapplied as Watson Manufacturing Company uses a predetermined rate of 75% of direct labor to apply overheads to the jobs.  It is underapplied when the actual overhead expense is higher than the applied costs, and vice versa.

d) The unit cost of Jobs 101 and 103 is determined by summing the direct material, labor, and overhead applied costs and then dividing by the number of units produced.

e) Job 102 was not completed during the period, and its costs are transferred to the Work In Process Inventory.
