Final answer:
The transaction for purchasing office supplies would be recorded in the cash disbursements journal with a debit to office supplies expense and a credit to the cash account.
Step-by-step explanation:
The transaction where a check number 284 is issued in the amount of $352.50 to Office Co. for office supplies invoice 282 would be recorded in the cash disbursements journal. In this journal, the office supplies expense would be debited for the amount of $352.50, representing the cost of the office supplies that were purchased. Conversely, the credits would be made to the cash account as the payment is made through a check, reducing the company's cash balance by the corresponding amount.
