If a check correctly written and paid by the bank for $633 is incorrectly recorded on the company's books for $678, the appropriate treatment on the bank reconciliation would be to increase or (decrease) the company's cash amount by $ . Use a positive number to indicate an increase and a minus sign for a decrease. Insert zero if the bank's cash balance should be adjusted rather than the company's. Insert whole numbers only (no dollar signs, decimals, etc.)
