Golden Arches
(page 57)

Here's a solution from a group of students (we don't know where they are...):

We worked on the problem Golden Arches. To do so we made two graphs. One was on paper and the other was on a TI-83 graphing calculator. Number of stores was plotted on the y-axis and year was located on the x-axis. Both brought us to the conclusion that number of stores in and outside of the U.S. would intersect in 2021.
Students involved,

Thank you, Brian, Bruce, and Evan!

And thank you for your clear description of what you did.
