Final answer:
To complete the recording of the transaction, the accountant needs to credit a different asset account for $500.
Step-by-step explanation:
To complete the recording of the transaction, the accountant needs to credit a different asset account for $500. This will ensure that the accounting equation remains balanced, as debits and credits must always be equal. In this case, the initial debit of $1,000 to the asset account needs to be offset by a credit of $500 to another asset account, resulting in a net debit of $500.
