Answer:
$17,100 underapplied
Explanation:
The computation of the manufacturing overhead is shown below:
Predetermined overhead rate is
= Estimated manufacturing overhead ÷ Estimated direct labor hours
= $738,000 ÷ 30000
= $24.6 per direct labor hour
now
Manufacturing overhead applied is
= Actual direct labor hours × Predetermined overhead rate
= 31500 × 24.6
= $774,900
Now
Underapplied manufacturing overhead is
= $792,000 - $774,900
= $17,100 underapplied
