## Module Solving Linear Inequalities

Eighth grade Lesson in Math Inequality Word Problems. Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem. For example: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100., From there, we have all of the pieces of the inequality in order and we can easily write the inequality. [Slide 4] has the inequality that the students should now be able to solve and then graph. [Slide 5] is a new problem without the color coding. I pretty much skipped this slide and went straight to [slide 6] which does have the color coding..
