Final answer:
The correct closing entry for the revenue accounts is to debit the Retained earnings account by $72,200 and credit the Revenue accounts by $72,200.
Step-by-step explanation:
The correct closing entry for the revenue accounts can be determined by transferring the total revenues to the Retained earnings account. Since the Retained earnings account has a credit balance of $54,000, we need to increase it by the total revenues of $72,200. This can be done by debiting the Retained earnings account by $72,200. The corresponding credit entry will be made to the revenue accounts, which will be a total of $72,200. The closing entry for the revenue accounts is therefore:
Debit Retained earnings: $72,200
Credit Revenue accounts: $72,200
