Answer:
$544,120
Step-by-step explanation:
Calculation for what The estimated manufacturing overhead at the beginning of the year used in the predetermined overhead rate must have been
First step is to calculate the Applied manufacturing overhead
Applied manufacturing overhead = $538,980 - $24,140
Applied manufacturing overhead = $514,840
Second step is to calculate the Predetermined overhead rate using this formula
Predetermined overhead rate = Applied manufacturing overhead / Actual direct labor hours
Let plug in the formula
Predetermined overhead rate = $514,840 / 21,100
Predetermined overhead rate = $24.4
Now let calculate the Estimated total manufacturing overheads using this formula
Estimated total manufacturing overheads = Estimated direct labor hours * Predetermined overhead rate
Let plug in the formula
Estimated total manufacturing overheads= 22,300 *$24.4
Estimated total manufacturing overheads= $544,120
Therefore The estimated manufacturing overhead at the beginning of the year used in the predetermined overhead rate must have been $544,120
