Answer:
I suppose that the requirement is correcting the errors in postings by a way of journal entries.
Debit Accounts receivable $90
Credit Cash $90
Dr Printer asset account $340
Cr Supplies $340
Debit Accounts receivable $670
Debit salaries & wages $775
Credit account payable $54
Debit retained earnings $600
Credit salaries and wages $600
Step-by-step explanation:
Actual cash received was $670 but $760 was posted to both accounts,hence $90 should credited to cash $90 and the same debited to accounts receivable.
Credit of $340 to accounts payable was correct,only the debit entry needs be reversed by crediting supplies and debiting Printer account.
The entry for revenue was correct but the debit was for a wrong amount.Hence Debiting accounts receivable with $630 takes care of that.
Salaries and wages would debited with $775
Accounts was debited $260 instead of $206,hence we credit accounts payable with $54 ($260-$206)
The dividends debited to salaries and wages should be reversed by crediting salaries and wages and debiting retained earnings
