Word problems that lead to inequalities

Word Problem Solving Strategies Read through the entire problem. Highlight the important information and key words that you need to solve the problem. Identify and define your variables. Write the equation or inequality. Solve. Write your answer in a complete sentence. Check or justify your answer (optional).

Inequality Key Words Is at least - means greater than or equal to Is At most –means less than or equal to Is no more than - means less than or equal to Is more than - means greater than Is less than - means less than Between -means compound inequality with and Inclusive -means “make the or equal to line”

Inequality Key Words minimum - means greater than or equal to maximum - means less than or equal to

System of equations Word Problems

Helpful Hints Read each problems twice. The second time - use your highlighter to highlight the key words. Focus on the inequality symbol and make sure that it makes sense in relation to the context of the problem. As you create your graph, remember that only the part that is shaded by bothinequalities is the solution area!
