## Key Concepts

**Finding the Total Value for Coins of the Same Type**- For coins of the same type, the total value can be found as follows: [latex]\begin{array}{c}\text{number}\cdot \text{value}=\text{total value}\hfill \end{array}[/latex]where
*number*is the number of coins,*value*is the value of each coin, and*total value*is the total value of all the coins.

**Solve a Coin Word Problem****Read**the problem. Make sure you understand all the words and ideas, and create a table to organize the information.**Identify**what you are looking for.**Name**what you are looking for. Choose a variable to represent that quantity.- Use variable expressions to represent the number of each type of coin, and write them in the table.
- Multiply the
*number*times the*value*to get the*total value*of each type of coin.

**Translate**into an equation. Write the equation by adding the total values of all the types of coins.**Solve**the equation using good algebra techniques.**Check**the answer in the problem and make sure it makes sense.**Answer**the question with a complete sentence.

- You may find it helpful to put all the numbers into a table to make sure they check.
