Answer:
Unitary cost= $78.07
Step-by-step explanation:
First, we need to calculate the predetermined overhead rate:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 4,547,200 / 80,000
Predetermined manufacturing overhead rate= $56.84 per direct labor hour
Now, we can allocate overhead:
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated MOH= 56.84*0.8= $45.47
Finally, the unitary cost:
Unitary cost= 15 + 17.6 + 45.47
Unitary cost= $78.07
