Final answer:
To post the journal entry, debit $200 to the Rent Expense account and credit $200 from the Cash account, reflecting an increase in expenses and a decrease in assets respectively.
Step-by-step explanation:
To post the journal entry for rent expense to the ledger, you would first enter the debit side. You would debit the Rent Expense account because expenses increase with debits. So, you would add $200 to the debit side of the Rent Expense ledger account. Next, you would post the credit side of the entry. You credit the Cash account because cash is an asset, and assets decrease with credits. Therefore, you would subtract $200 from the Cash ledger account's credit side. These entries help maintain the accounting equation and track the business's financial transactions.
