The purpose of this task is for students to represent relationships between quantities in a context with equations and interpret the resulting system of equations in the context. This task has a wide array of uses: it could be an introductory task to systems of equations or used in assessment. The task initially has the students write out different equations for two different scenarios. Then the students can consider the two equations together, which naturally leads into a discussion on the point of intersection of two graphs and into systems of equations.
