MAFS.7.EE.2.4: Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.
a. Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For
example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width?
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.

About Media4Math
Our Mission
Media4Math's mission is to educate 21st-century students in real-world applications of math with digital technology. We bring math to life in your classroom with a rich blend of resources to inspire your students to learn. Our philosophy is that the procedural side of math is a prerequisite to using it, but we also find that real-world math applications can provide motivation and even inspiration for math students. Math is its own language and it has important stories to tell. While many of our resources are for procedural skills, there are many resources that are real-world applications of math. Some of these resources rely on partnerships with other educational publishers.
