Answer:
$48.23 per direct labor hour
Explanation :
Pre-determined overhead rate = Budgeted Overheads ÷ Budgeted Activity
where,
Budgeted Overheads = $52,000 + $15,000 + $42,000 + $18,000 + $48,000 + $75,000 + $108,800 = $358,800
Budgeted Activity (direct labor-hours) = 8,000 hours
therefore,
Pre-determined overhead rate = $358,800 ÷ 8,000 hours = $48.23 per direct labor hour
The company's pre-determined overhead rate, assuming that the company uses a Single plantwide predetermined overhead rate based on direct labor-hours is $48.23 per direct labor hour.
