### Component

**7.EE.4.b:** 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. Write an inequality for the number of sales you need to make,
and describe the solutions.
