Answer:
Under/over applied overhead= 13,600 underapplied
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= 266,400/18,500
Predetermined manufacturing overhead rate= $14.4 per machine hour
Now, we can allocate overhead:
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated MOH= 14.4*19,050
Allocated MOH= $274,320
Finally, the over/under allocation:
Under/over applied overhead= real overhead - allocated overhead
Under/over applied overhead= 287,920 - 274,320
Under/over applied overhead= 13,600 underapplied
