Answer:
$32.41
Explanation:
Given that,
Estimated machine-hours = 19,000
Estimated variable manufacturing overhead = $ 7.89 per machine-hour
Estimated total fixed manufacturing overhead = $ 465,880
Actual machine-hours for the year = 20,200
Predetermined overhead rate is defined as the sum total of estimated variable manufacturing overhead per machine hour and estimated total fixed manufacturing overhead per machine hour.
Firstly, we need to find out the Estimated total fixed manufacturing overhead per machine hour:
= Estimated total fixed manufacturing overhead ÷ Estimated machine-hours
= $ 465,880 ÷ 19,000
= $24.52 per machine hour
Therefore, the predetermined overhead rate is as follows:
= Estimated variable manufacturing overhead + Estimated total fixed manufacturing overhead
= $7.89 per machine hour + $24.52 per machine hour
= $32.41
