    Which of these gas pumps are trying to rip you off?

  • 1.

    What's your best guess? Why?

  • Teacher note
    Host a debate here. Invite students to share their reasons. I'd expect some will think the third pump is a ripoff because it's moving faster.

Act Two

  • Teacher note
    Invite your students to head to Desmos and plot data for each pump. We're hoping that a graphical representation will reveal trends that our eyes can't detect.
