Answer:
(DR) Income Summary 38,600
(CR) Retained Earnings 38,600
and
(DR) Retained Earnings 18,000
(CR) Dividends 18,000
Explanation:
Since the revenue and expense have zero balances, it means that the Echo corporation's accountant completed the closing entry for those account.
The remaining items to be closed is the Income Summary and Dividends account. Simply put those accounts on the opposite side of their balance.
Income summary has a credit balance of 38,600 (347,400-308,800)
So we have to debit Income Summary and the corresponding credit is Retained Earnings.
Next, dividends has a debit balance of $18,000 so just credit dividends and debit retained earnings to complete the closing procedures.
