Answer:
Results are below.
Step-by-step explanation:
To calculate the predetermined manufacturing overhead rate we need to use the following formula:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Direct labor cost:
Predetermined manufacturing overhead rate= 900,000 / 500,000
Predetermined manufacturing overhead rate= $1.8 per direct labor dollar
Direct labor hours:
Predetermined manufacturing overhead rate= 900,000 / 50,000
Predetermined manufacturing overhead rate= $18 per direct labor hour
Machine-hour:
Predetermined manufacturing overhead rate= 900,000 / 100,000
Predetermined manufacturing overhead rate= $9 per machine hour
