Answer:
Predetermined manufacturing overhead rate= $57 per direct labor hour
Explanation:
First, we need to calculate the total estimated overhead:
Total estimated overhead= 200,000 + 100,000 + 84,000 + 300,000
Total estimated overhead= $684,000
Total direct labor hours= 9,000 + 3,000= 12,000
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
Predetermined manufacturing overhead rate= 684,000/12,000
Predetermined manufacturing overhead rate= $57 per direct labor hour
