Answer:
Results are below.
Explanation:
<u>First, we need to calculate the predetermined overhead rate:</u>
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 11,100,000/160,000
Predetermined manufacturing overhead rate= $69.375 per machine hour
<u>Now, we can allocate overhead:</u>
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated MOH= 69.375*81,000
Allocated MOH= $5,619,375
<u>Finally, we can determine the under/over allocation:</u>
Under/over applied overhead= real overhead - allocated overhead
Under/over applied overhead= 7,950,000 - 5,619,375
Under/over applied overhead= $2,330,625 underallocated
