Explanation:

1. Recording transactions in the general journal involves debiting the account that receives value and crediting the account that supplies value.

2. A review of the general ledger and the trial balance tabs showed the effects of the transactions on the account balances and the new accounts created with the new transactions.

3. Adjusting entries for:

a) Rent: This accrued the rent for the month of January.  The amount reduced the Rent Prepaid account.

b) Supplies: The cost of supplies used was determined as the difference between the sum of opening supplies and purchases less the closing supplies.  The cost of supplies reduces the Supplies account to the closing balance of $3,500.

c) Deferred Revenue was reduced by the amount of services already provided.  This is in accordance with the accrual concept and matching principles of Generally Accepted Accounting Principles.
