Answer:
since $100 worth of 2022 wages were reported ion 2023, the wages expense account for 2023 will be overstated by $100, so net income 2023 will be understated by $100.
Even thought the net income 2023 was understated, the retained earnings account will not be understated. This is because the net income 2022 was overstated by $100, which will offset the understatement of the net income 2023 account.
Wages expense is a temporal account which must be closed at the end of the accounting period, while retained earnings is a permanent account that is carried from one year to another.
