Answer:
$38.45
Step-by-step explanation:
The computation of the predetermined overhead rate is shown below:
= Estimated variable manufacturing overhead per machine hour + estimated fixed manufacturing overhead per machine hour
where,
Estimated variable manufacturing overhead = $10.75
Estimated fixed manufacturing overhead is
= $648,180 ÷ 23,400 machine hours
= $27.70
So, the predetermined overhead rate is $38.45
