Answer:
36,250 direct labor- hours
Step-by-step explanation:
Calculation to determine what the estimated direct labor-hours at the beginning of the year used in the predetermined overhead rate must have been:
First step is to calculate the Manufacturing overhead applied using this formula
Manufacturing overhead applied = Actual overhead + Overapplied overhead
Let plug in the formula
Manufacturing overhead applied= $972,000 + $65,115
Manufacturing overhead applied= $1,037,115
Second step is to calculate the Predetermined overhead rate using this formula
Predetermined overhead rate = Manufacturing overhead applied ÷Actual direct labor-hours
Let plug in the formula
Predetermined overhead rate= $1,037,115÷ 36,390 direct labor-hours
Predetermined overhead rate = $28.50 per direct labor-hour
Now let calculate the Estimated direct labor-hours using this formula
Estimated direct labor-hours = Estimated total manufacturing overhead ÷Predetermined overhead rate
Let plug in the formula
Estimated direct labor-hours= $1,033,125 ÷$12.50 per direct labor-hour
Estimated direct labor-hours= 36,250 direct labor- hours
Therefore the estimated direct labor-hours at the beginning of the year used in the predetermined overhead rate must have been:36,250 direct labor- hours
