Are hybrid cars worth the extra cost? Many vehicles are available with both standard gas-powered engines or hybrids. While the hybrid models require less gas and are better for the environment, they may initially cost thousands of dollars more.

In this lesson, students use linear equations to compare the costs of driving a car with a standard engine versus a hybrid engine and debate whether new buyers should always go green

### Students will

• Write and solve equations to solve real-world questions
• Compare proportional relationships represented in different forms including: tables, graphs, and equations

### Before you begin

Some experience solving equations will be helpful but not required.
