### Requirements

Students explore two new scenarios that involve solving systems of equations. The first situation involves the travel time for a round trip on an airplane, while the second situation involves calculating the numbers of students and adults attending a high school musical. By the end of this lesson, students will improve their understanding of how using mathematics to model a real-life situation with two variables can help them solve problems. This is the last of seven activities for teaching and learning linear equations in algebra: Ski Slope; y=mx+b; Points, Intercepts, and Slopes, Oh My!; Linear Word Problems; Solving Systems of Equation by Graphing; Systems of Equations Word Problems Part 1; Systems of Equations Word Problems Part 2.

» Lesson Plan and Student Assessment documents are also available.
