**Intro**

When you use a credit card, you must pay your bill on time in order to avoid extra costs. If you do not make the minimum payment on your credit card bill by the due date, the credit card company charges a late fee. The company may also raise your interest rate.

**Example Calculating Costs of Missing a Credit Card Payment**
