7-110.

Brian was holding a ballroom dance. He wanted to make sure girls would come, so he charged boys $$5$ to get in but girls only$$3$. The $45$ people who came paid a total of \$$175$. How many girls came to the dance?

Set up a system of equation, where we let $b =$ boys and $g =$ girls.

Review the Math Notes box in Lesson 6.3.3 on the Elimination Method for systems of equations.

$25$ girls came to the dance.
