Prepare a presentation comparing what is similar and what is different between the book problem and the shoe problem.

# Challenge Problem

- Look back at the graph you made in the previous lesson representing the relationship between the price and total cost of items at a 5% tax. Compare it to the two graphs you made in this lesson. If the scales on the axes of any of the graphs are different, re-create the three graphs on the same coordinate plane.
- How does the steepness of each graph compare with the steepness of the other graphs? Identify the constant of proportionality in each relationship.
