Predetermined overhead rate </h3>
a. Predetermined overhead rate
Predetermined overhead rate = Variable overhead cost per machine hour + Fixed manufacturing overhead cost/Estimated machine hours
Predetermined overhead rate= 4.60 + 652,000/159,000
Predetermined overhead rate= 4.60 + 4.10
Predetermined overhead rate= $8.7 per machine hour
b. Overhead applied
Overhead applied = Actual machine hours used x Predetermined overhead rate
Overhead applied = 34x 8.7
Overhead applied= $295.8
Overhead applied= $296 (rounded to nearest whole dollar)
c. Total manufacturing cost assigned to Job 400.
Job cost sheet
