Answer:
$165,000
Step-by-step explanation:
The computation of the amount of over- or underapplied overhead is shown below:
The Predetermined overhead rate is
= Predetermined overhead ÷ direct labor cost
= ($300,000 ÷ $200,000)
= 150% of direct labour cost
Now
overhead applied is
= (150% × $280,000)
= $420,000
And,
Actual overhead=$255,000
So,
overhead overapplied is
= $420,000 - $255,000
= $165,000
