Answer:
Underapplied overhead= $109,500
Step-by-step explanation:
First, we need to calculate the predetermined overhead rate:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 525,000 / 150,000
Predetermined manufacturing overhead rate= $3.5 per direct labor hour
Now, we can allocate overhead:
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated MOH= 3.5*135,000
Allocated MOH= $472,500
Finally, the under/over applied overhead:
Under/over applied overhead= real overhead - allocated overhead
Under/over applied overhead= 582,000 - 472,500
Underapplied overhead= $109,500
