The receipt of $8,400 for services rendered was recorded as a debit to Accounts Receivable and a credit to Fees Earned. b. The purchase of supplies of $2,500 on account was recorded as a debit to Office Equipment and a credit to Supplies. Journalize the entries on March 1 to correct the errors. Use two entries to correct the error described in (b). (That is, record an entry to reverse the incorrect entry and a second entry to record the correct entry.)
