When you purchase supplies on account, it means you are buying supplies on credit. This transaction should be recorded in your accounting records as follows:
Debit to Supplies Expense: This increases the supplies expense account, reflecting the cost of the supplies purchased.
Credit to Accounts Payable: This increases the accounts payable account, reflecting the amount you owe to the supplier.
Therefore, the correct entry is:
Debit Supplies Expense and Credit Accounts Payable.
This means the correct answer is:
c) a debit to supplies expense and a credit to accounts payable.
