Common Core Identifier: 7.EE.4b / Grade: 7

Curriculum: Expressions And Equations: Solve Real-Life And Mathematical Problems Using Numerical And Algebraic Expressions And Equations.

Detail: 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.
