Solving and Graphing Linear Inequalities in Context

Question:
A savings account currently holds 45 dollars. The goal is to have more than 120 dollars saved before making a purchase. Write and solve an inequality to find the minimum additional amount d, in dollars, that must be saved. Graph the solution and interpret it in context.

Solving and Graphing Linear Inequalities in Context

This lesson walks through writing and solving a one-variable linear inequality based on a real-world savings scenario. Students learn to isolate the variable, graph the solution on a number line with an open circle, and interpret what the solution means in context.

In this lesson, you will learn to:
• Write a linear inequality from a real-world context
• Solve a one-step linear inequality by applying inverse operations
• Graph the solution set on a number line, correctly using open or closed circles
• Interpret and verify the solution in the context of the o
