Answer:
$165,000
Step-by-step explanation:
Calculation for what is the total amount credited to the manufacturing overhead account for the year for Grey
First step is to calculate Predetermined overhead rate using this formula
Predetermined overhead rate = Estimated overhead costs / Estimated machine hours
Let plug in the formula
Predetermined overhead rate = $220,000 / 20,000 machine hours
Predetermined overhead rate= $11
Second step is to calculate Total amount credited to the factory overhead account for the year for Grey
Using this formula
Total amount credited to the factory overhead account for the year for Grey = Predetermined overhead rate × Actual machine hours
Let plug in the formula
Total amount credited to the factory overhead account for the year for Grey= $11 × 15,000 machine hours
Total amount credited to the factory overhead account for the year for Grey = $165,000
Therefore the Total amount credited to the factory overhead account for the year for Grey will be $165,000
