Whichever option you choose, justify your reasoning with mathematics.
Research about concession sales
For a more interesting debate, pull up a local sports team and find out their cost of parking and a few of their items for sale in the concession stand. This could be an incredible discussion. If you attempt this with your students, I would sincerely appreciate a comment, tweet, or email that explains what you did with it, what you would change, and how it went. Thank you!
