$490,500 underapplied
Explanation:
The computation of the overhead is shown below:
But before that the predetermined overhead rate and the applied overhead is
Predetermined overhead rate is
= Estimated overhead ÷ estimated activity
= $10,282,000 ÷ 194,000
= $53 per MH
Now
Applied overhead = actual activity × overhead rate
= 98,100 hours ×$53 per MH
= $5,199,300
Now the underapplied overhead is
= $5,689,800 - $5,199,300
= $490,500 underapplied
