Final answer:
The total factory overhead applied during September is $115,500.
Step-by-step explanation:
The total factory overhead applied during September can be calculated by multiplying the predetermined overhead rate by the actual direct labor hours used in the jobs. In this case, we need to calculate the predetermined overhead rate using the estimated direct labor hours and estimated factory overhead. The predetermined overhead rate is calculated as follows:
Predetermined Overhead Rate = Estimated Factory Overhead / Estimated Direct Labor Hours
Predetermined Overhead Rate = $1,001,000 / 130,000
Predetermined Overhead Rate = $7.70 per direct labor hour
Now, we can calculate the total factory overhead applied for the completed Job X and started but not finished Job Y in September.
Job X used 10,000 direct labor hours, so the factory overhead applied for Job X is: $7.70 per direct labor hour * 10,000 direct labor hours = $77,000
Job Y started but not finished, so we need to estimate the direct labor hours used. Let's say Job Y used 5,000 direct labor hours. Then, the factory overhead applied for Job Y is: $7.70 per direct labor hour * 5,000 direct labor hours = $38,500
Therefore, the total factory overhead applied during September is $77,000 + $38,500 = $115,500.
