Answer:
Overhead at the end of the year was $3,570 under-applied
Step-by-step explanation:
For computing the ended overhead amount, first, we have to compute the predetermined overhead rate. The formula is shown below:
Predetermined overhead rate = (Total estimated manufacturing overhead) ÷ (estimated direct labor-hours)
= $521,220 ÷ 21,900 hours
= $23.8
Now we have to find the actual overhead which equals to
= Actual direct labor-hours × predetermined overhead rate
= 21,750 hours × $23.8
= $517,650
So, the ending overhead equals to
= Actual manufacturing overhead - actual overhead
= $521,220 - $517,650
= $3,570 under-applied
