Answer:
If overhead was overapplied, then the COGS should be debited overhead.
The correct answer is B.
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= 400,000 / 20,000
Predetermined manufacturing overhead rate= $20 per DLH
Now, we allocate overhead:
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated MOH= 20*21,000
Allocated MOH= $420,000
Finally, the over/under allocation:
Under/over applied overhead= real overhead - allocated overhead
Under/over applied overhead= 415,000 - 420,000
Overapplied overhead= $5,000
If overhead was overapplied, then the COGS should be debited overhead.
