Answer:
She forgot about the interest rate.
Step-by-step explanation:
Maya most likely forgot about the interest rate. Credit card companies allow you to purchase goods that you are not going to pay for immediately. This means that you will owe this amount to the company. When you pay your total balance before the due date each month, you will only pay the amoun that you have actually spent. However, if you do not pay in full, interests are charged, which lead you to pay more than you originally spent.
