Answer:
-$28,200
Step-by-step explanation:
when the inventory closing balance is overstated, the cost of goods sold is understated and as such the net income which is posted to the retained earnings will be overstated.
For the overstatement of depreciation, the net income will be understated by the same amount.
The reverse is the effect on net income for these items where the misstatement is otherwise.
Retained earnings adjustments required on January 1, 2022
= -$60,000 + $25,700 + $12,500 - $6,400
= -$28,200
