Answer:

Unitary cost= $155.8

Explanation:

First, we need to determine the overhead allocation rate:

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

Predetermined manufacturing overhead rate= (562,400/76,000) + 2.3

Predetermined manufacturing overhead rate= $9.7 per machine hour

Now, we can calculate the total cost of Job A496:

Number of units in the job 20

Total machine-hours 80

Direct materials $780

Direct labor cost $1,560

Total cost= 780 + 1,560 + (9.7*80)

Total cost= $3,116

Finally, the unitary cost:

Unitary cost= 3,116/20

Unitary cost= $155.8
