With this problem, students are able to see an example of a real-world situation and understand how to answer a question about two different scenarios and see how they relate to one another.  It is important that students can see and understand that anything in the world can be related or traced back to math.  This is just one example.

Students in this lesson will have to understand proportional relationships between two linear equations then be able to create those equations from what they already know about what the equation for a line even looks like.  Students will be asked to graph their solutions in a table in order to see the comparisons of the two different car salesman and understand that even though an initial amount may be more than another, over a period of time the rate of change is more important to see who will make more at the end of the year.
