Answer:
Factory Overhead Balance= $55,000.
Explanation:
Over-applied overhead = Assigned Overhead − Actual Overhead
Where Assigned Overhead= Actual Direct Labor×Overhead rate
Where Overhead rate = Estimated overhead
/ Estimated Direct Labor * 100
Overhead rate= 600000/300000 * 100
Overhead Rate= 200%
Assigned Overhead = 335,000 * 200%
Assigned Overhead = 670,000
Therefore, the assigned overhead to be applied is $670,000.
Now, Over-applied overhead = Assigned Overhead − Actual Overhead
Factory Overhead = $670,000 - $615,000
Factory Overhead Balance= $55,000.
