Answer:
a. $500,000 overapplied
Explanation:
Thomlin Company uses machine hours to calculate predetermined overhead rate. The predetermined overhead rate based on forecast was;
$15,000,000 / 300,000 machine hours = $50 per machine hour
The current overheads based on predetermined overhead rate :
330,000 machine hours * $50 per machine hour = $16,500,000
Actual overheads for the year = $16,000,000
Difference between allocated and actual overheads:
$16,500,000 - 16,000,000 = $500,000 overapplied.
