Answer:
$7.8 per direct labor hour
Step-by-step explanation:
The formula to compute the predetermined overhead rate is shown below:
Predetermined overhead rate = (Total estimated manufacturing overhead) ÷ (estimated direct labor-hours)
where,
Total estimated manufacturing overhead = Actual manufacturing overhead - under applied overhead
= $80,000 - $2,000
= $78,000
And, the estimated direct labor hours is 10,000
So, the predetermined overhead rate is
= $78,000 ÷ 10,000
= $7.8 per direct labor hour
