Final answer:
To calculate the predetermined overhead rate, divide the estimated overhead by the estimated activity base. In this case, we can calculate the rate using direct labor hours, direct labor dollars, and machine hours.
Step-by-step explanation:
To calculate the predetermined overhead rate, we divide the estimated overhead by the estimated activity base. In this case, we have three activity bases: direct labor hours, direct labor dollars, and machine hours.
First, we calculate the predetermined overhead rate using direct labor hours:
Predetermined overhead rate = Estimated Overhead / Estimated Direct Labor Hours
Predetermined overhead rate = $375,000 / 125,000 hours = $3 per hour
Next, we calculate the predetermined overhead rate using direct labor dollars:
Predetermined overhead rate = Estimated Overhead / Estimated Direct Labor Dollars
Predetermined overhead rate = $375,000 / $1,500,000 = $0.25 per dollar
Finally, we calculate the predetermined overhead rate using machine hours:
Predetermined overhead rate = Estimated Overhead / Estimated Machine Hours
Predetermined overhead rate = $375,000 / 15,000 hours = $25 per hour
