Lois bought clothing at a store. She did not have enough in her bank account to pay for the purchase. After receiving the bill and paying off the balance, she realized that she paid $9.69 in interest. Which statement is true about her method of payment?

A debit card uses money directly from a bank account, so it would not create a bill with interest. Lois was billed and paid $9.69 in interest, which means she borrowed money through a credit card and did not avoid interest by paying the full balance by the due date. Therefore, the true statement is that Lois used a credit card to make the purchase.
