In this lesson, you will learn how to solve a coin problem with the help of a chart. The problem involves figuring out the number of dimes and quarters Ed has based on the given information that he has six more quarters than dimes and the total value of his coins is $6.5. By defining variables and using the unit value of each coin, you will be able to set up an equation that can be solved to find the number of each coin. Lastly, you will learn how to check your answer to ensure that it is correct.
