Answer:
$8 per direct labor hour
Explanation:
1. The computation of the plant wide overhead rate is shown below:
But before that first we have to find out the direct labor hours used which is
= Direct labor cost ÷ direct labors per hour
= $345,000 ÷ $15
= $23,000
Now the predetermined overhead rate is
= Manufacturing overhead applied ÷ direct labor hours
= $184,000 ÷ 23,000
= $8 per direct labor hour
