Answer:
$3.73 per direct labor-hour
Step-by-step explanation:
The computation of the predetermined overhead rate is shown below:
= (Total estimated manufacturing overhead) ÷ (estimated direct labor-hours)
where,
Total estimated manufacturing overhead = Total fixed manufacturing overhead cost + variable manufacturing overhead cost
= $13,000 + $15,000
= $28,000
And, the direct labor hour is 7,500
So, the predetermined overhead rate is
= $28,000 ÷ 7,500 direct labor hours
= $3.73 per direct labor-hour
