Case 2. A fire destroyed certain accounting records of DuPont Science Corp. The owner. Franois DuPont, asks for your help in reconstructing the records. He needs to know the begin- ning and ending balances of Accounts Receivable and the credit sales and cash receipts on account from customers during March. All of DuPont's sales are on credit, with payment terms of 2/10 n/30. All cash receipts on account reached DuPont within the 10-day discount period, except as noted. Round all amounts to the nearest dollar. The only accounting record preserved from the fire is the accounts receivable subsidiary ledger, which appears on page 265.
