Required:

1. Journalize the transactions (in chronological order as presented in the data) for October. Use a purchases journal and a cash payments journal, and a two-column general journal. Use debit columns for Field Supplies, Office Supplies, and Other Accounts in the purchases journal. Refer to the following partial chart of accounts:

11	Cash	18	Office Equipment
14	Field Supplies	19	Land
15	Office Supplies	21	Accounts Payable
16	Prepaid Rent	61	Salary Expense
17	Field Equipment	71	Rent Expense

At the points indicated in the narrative of transactions, post to the following subsidiary accounts in the accounts payable ledger:

A-One Office Supply Co.

Midland Supply Co.

Petro Services Inc.

2. Post the individual entries in chronological order (Other Accounts columns of the purchases journal and the cash payments journal; 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 ledge in chronological order. However, if there is more than one entry on the same date, post from the purchases journal before posting from the cash payments journal.r.

If no other account is needed in the "Other Accounts Dr." column select "No Entry Required". For those boxes in which no entry is required, leave the box blank.

4. Sum the balances of the accounts payable creditor balances.

5. All are reasons why West Texas might consider using a subsidiary ledger for the field equipment EXCEPT:
