Answer:
net income = $258,000
total assets = $1,800,000
Step-by-step explanation:
since the inventory was overstated at the beginning of the year, the COGS were overstated, reducing net income by $18,000. So the adjustment at the end of the year should increase net income by $18,000.
Last year both assets and retained earnings were overstated by the error, so this year they must be adjusted. Since net income increases, then retained earnings should increase, this will offset any change in the balance sheet. The same applies to assets, last years overstating of inventory will be offset by this year's understating.
