Question : The balance in the Finished Goods inventory account at the beginning of the year was:
A. $15,900
B. $15,400
C. $21,200
D. $36,600
Answer was shown as : Ending finished goods inventory = Beginning finished goods inventory + Debits - Credits
$36,600 = Beginning finished goods inventory + $360,000 - $338,800
Beginning finished goods inventory = $36,600 - $360,000 + $338,800 = $15,400
I do not get why this is, and where the debits and credits come from and where the beginning balance comes from. Thanks.
