Use debit columns for Field Supplies, Office Supplies, and Other Accounts in the pur- chases journal. Refer to the following partial chart of accounts: 11 Cash 19 Land 21 Accounts Payable 61 Salary Expense 71 Rent Expense 14 Field Supplies 15 Office Supplies 17 Field Equipment At the points indicated in the narrative of transactions, post to the following accounts in the accounts payable subsidiary ledger: Best Office Supply Co. Hydro Supply Co. Pure Equipment Co. 2. Post the individual entries (Other Accounts columns of the purchases journal and the cash payments journal and both columns of the general journal) to the appropriate general ledger accounts. 3. Total each of the columns of the purchases journal and the cash payments journal and post the appropriate totals to the general ledger. (Because the problem does not include transactions related to cash receipts, the cash account in the ledger will have a credit balance.) 4. Prepare a schedule of the accounts payable creditor balances. 5. Why might AquaFresh consider using a subsidiary ledger for the field equipment?
