Explanation:
The computation is shown below:
A.
Predetermined overhead rate = (Total estimated manufacturing overhead) ÷ (estimated machine labor-hours)
= $357,000 ÷ 8,500 hours
= $42
B. Now we have to find the applied overhead which equal to
= Actual machine labor-hours × predetermined overhead rate
= 8,560 hours × $42
= $359,520
C.
So, the ending overhead equals to
= Actual manufacturing overhead - applied overhead
= $358,000 - $359,520
= $1,520 over-applied
