Answer:
36,250 direct labor-hours
Step-by-step explanation:
a. Underapplied (overapplied) manufacturing overhead = Actual manufacturing overhead - Manufacturing overhead applied
- $65,115 = $972,000 - Manufacturing overhead applied
Manufacturing overhead applied = $972,000 + $65,115 = $1,037,115
b. Manufacturing overhead applied = Predetermined overhead rate × Actual direct labor-hours
Therefore, we have:
Predetermined overhead rate = Manufacturing overhead applied ÷ Actual direct labor-hours = $1,037,115 ÷ 36,390 = $28.50 per direct labor-hour
c. Estimated direct labor-hours = Estimated total manufacturing overhead ÷ Predetermined overhead rate = $1,033,125 ÷ $28.50 = 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.
