Answer:
Results are below.
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= 478,800 / 26,600
Predetermined manufacturing overhead rate= $18 per machine hour
Now, we can allocate overhead:
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated MOH= 18*54,000
Allocated MOH= $972,000
Finally, the over/under allocation:
Under/over applied overhead= real overhead - allocated overhead
Under/over applied overhead= 986,000 - 972,000
Underallocated overhead= $14,000
