Explanation:

Giving the following information:

The company based its predetermined overhead rate for the current year on total fixed manufacturing overhead cost of $481,900, variable manufacturing overhead of $3.00 per machine-hour, and 79,000 machine-hours.

Job A496:

Number of units in the job 20

Total machine-hours 80

Direct materials $ 870

Direct labor cost $1,740

First, we need to calculate the estimated manufacturing overhead rate we need to use the following formula:

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

Estimated manufacturing overhead rate = (481,900/79,000) + 3 = $9.1 per machine hour

Now, we need to calculate the total cost per unit:

Unitary cost = direct material + direct labor + allocated overhead

Unitary cost = (879/20) + (1,740/20) + (80*9.1) / 20 = $167.35
