1. Lesson 5-5 Example 4 5-5 Solve. RENTAL CARS On vacation, Jamal wanted to rent a car. There was a base cost of $50 with an additional cost of $0.15 per mile. Jamal wanted to keep the cost of the car under $100. Write and solve an inequality to find m, the number of miles Jamal can drive. Graph the solution.

2. Lesson 5-5 Example 4 5-5 UnderstandRead the problem. Write what you know. The cost of renting a car was $50 plus $0.15 per mile. Jamal wants to keep the cost under $100.

3. Lesson 5-5 Example 4 5-5 PlanPick a strategy. One strategy to use is to draw a diagram for an equation.

4. Lesson 5-5 Example 4 5-5 SolveEach side of the model is not equal in value, so it is an inequality. Write the inequality. Jamal wants to spend less than $100 so you would use the sign, <. Write and solve the inequality. 50 + 0.15m < 100

5. Lesson 5-5 Example 4 5-5 Graph the inequality. Use a open circle because 333 is not a solution. Shade to the left of 333, because the inequality uses less than.

6. Lesson 5-5 Example 4 5-5 CheckSubstitute any number less than 333 for m to check.
