Answer:
Predetermined manufacturing overhead rate= $11.15 per machine hour
Explanation:
Molding Fabrication Total
Estimated total machine-hours used 2,500 1,500 4,000
Estimated total fixed manufacturing overhead $ 14,000 $ 17,400 $ 31,400
Estimated variable manufacturing overhead per machine-hour $ 3.00 $ 3.80
<u>To calculate a single plantwide predetermined overhead rate, we need to use the following formula:</u>
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Total fixed overhead= $31,400
Total variable overhead= (3*2,500) + (3.8*1,500)= $13,200
Total Machine hours= 4,000
Predetermined manufacturing overhead rate= (31,400 + 13,200) / 4,000
Predetermined manufacturing overhead rate= $11.15 per machine hour
