Answer:
COGS 3807 debit
FG 7896 debit
WIP 2397 debit
Factory Overhead 14,100 credit
--to record the underapplication of overhead--
Explanation:
overhead rate:
![\frac{Cost\: Of \:Manufacturing \:Overhead}{Cost \:Driver}= Overhead \:Rate](https://tex.z-dn.net/?f=%5Cfrac%7BCost%5C%3A%20Of%20%5C%3AManufacturing%20%5C%3AOverhead%7D%7BCost%20%5C%3ADriver%7D%3D%20Overhead%20%5C%3ARate)
$515,000 overhead / 515,000 labor cost = $1
each labor cost generates a dollar of overhead.
221,400 x 1 = 221,400 overhead in COGS
459,200 x 1 = 459,200 overhead in Finished Goods
139,400 x 1 = 139,400 overhead in WIP inventory
Total applied 820,000
Actual 805,900
Underapplied 14,100
Now we weight each concept and determiante the portion underapplocated in each concept
