Answer:
Underapplied by $3,000
Step-by-step explanation:
Calculation for what The Corporation's manufacturing overhead cost for the year was:
First step is to calculate the Predetermined Overhead rate
Predetermined Overhead rate=( $ 330,000/ 55,000)
Predetermined Overhead rate= $ 6 per labor hour
Now let calculate the Manufacturing overhead cost
Manufacturing overhead cost= (6 x 57 000)-$345,000
Manufacturing overhead cost=$342,000-$345,000
Manufacturing overhead cost=Underapplied by $3,000
Therefore The Corporation's manufacturing overhead cost for the year was:underapplied by $3,000
