Question

Kostelnik Corporation uses a job-order costing system with a single plantwide predetermined overhead rate based on machine-hours. The company based its predetermined overhead rate for the current year on total fixed manufacturing overhead cost of $285,600, variable manufacturing overhead of $2.70 per machine-hour, and 42,000 machine-hours. The company has provided the following data concerning Job A496 which was recently completed:
Number of units in the job 20
Total machine-hours 80
Direct materials $910
Direct labor cost $1,820
The unit product cost for Job A496 is closest to:_______.
A. $136.50 .
B. $173.30.
C. $34.12.
D. $43.33.

Answer 1

Answer:

The correct answer is B.

Explanation:

Giving the following information:

Estimated overhead= $285,600

variable manufacturing overhead= $2.70 per machine-hour

Estimated machine-hours= 42,000

Job A496:

Number of units in the job 20

Total machine-hours 80

Direct materials $910

Direct labor cost $1,820

First, we need to allocate overhead to Job A496:

Estimated manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Estimated manufacturing overhead rate= (285,600/42,000) + 2.7

Estimated manufacturing overhead rate= $9.5 per machine hour

Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base

Allocated MOH= 9.5*80= $760

Now, we can calculate the total cost:

Total cost= 910 + 1,820 + 760

Total cost= $3,490

Finally, we determine the unitary cost:

Unitary cost= 3,490/20= $174.5
