Answer:
Machine hours per unit= 18 / 0.5= 36
Explanation:
First, we need to calculate the predetermined manufacturing overhead rate using the following formula:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 103,000 / 206,000
Predetermined manufacturing overhead rate= $0.5 per machine hour
Now, we need to determine the allocated overhead:
Unitary cost= direct material + direct labor + allocated overhead
72= 18 + 36 + allocated overhead
18= allocated overhead
Finally, the machine hours per unit:
Machine hours per unit= 18 / 0.5= 36
