Answer:
Predetermined manufacturing overhead rate= $18 per direct labor hour
Step-by-step explanation:
First, we need to calculate the estimated overhead cost for the period:
Estimated overhead cost= Shop and repair equipment depreciation + Shop supervisor salaries + Shop property taxes + Shop supplies
Estimated overhead cost= 91,000 + 250,000 + 40,000 + 15,000
Estimated overhead cost= $396,000
To calculate the predetermined manufacturing overhead rate we need to use the following formula:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 396,000 / (550,000/25)
Predetermined manufacturing overhead rate= 396,000 / 22,000
Predetermined manufacturing overhead rate= $18 per direct labor hour
