Final answer:
Maranda Sellars, who pays off her credit card balance every month, is known as a transactor. This is a wise financial practice that helps avoid interest charges, as a credit card is essentially a short-term loan.
Step-by-step explanation:
Maranda Sellars, who pays off the balance on her credit card every month, is known as a transactor. A transactor is a type of credit card user who avoids accruing interest on their purchases by paying off the full balance of their credit card each statement period. Since a credit card operates essentially as a short-term loan, with the money being transferred from the credit card company's checking account to the seller, users like Maranda are employing a financially savvy method by not carrying a balance over into the next month, thereby avoiding additional charges that come from interest.
