Answer:
Net income is overstated by $28,000.
Explanation:
As the company forget to make the adjustment entry it didn't recognize any expense for the expired insurance.
From September to December 31th 4 month of insurance has expired:
42,000 x 4 month/6 months = 28,000 insurance expense
as the expense weren't post the income statement is overstated along with the assets of the company as it doesn't have a prepaid amount for 42,000 but for 14,000
