Answer: D. underapplied overhead of $6,000.
Step-by-step explanation:
First we find the Pre-determined overhead rate and we can see that the company estimated manufacturing overhead would be $150,000 and direct labour hours would be 10,000.
So the Pre-determined rate is,
= 150,000/10,000
= $15 per direct labour hour.
We then calculate the actual Applied Overhead. The actual direct labour was 12,000 so calculating we have,
= 15 * 12,000
= $180,000
Now we then calculate for the Underapplied or (Overapplied) manufacturing overhead amount.
The formula is,
Underapplied (Overapplied) Manufacturing = Actual Manufacturing Overhead - Applied Manufacturing Overhead
Underapplied (Overapplied) = 186,000 - 180,000
= $6,000
It is a positive number so it is $6,000 underapplied therefore option D is correct.
