Your movie fans will be interested in this resource. They will compare video streaming plans. One plan charges a set rate per month and a reduced viewing fee, and the other has a flat rate per each video viewed. Unfortunately, students only need to find an equation for each situation and determine how much three and five videos cost per month. It would be good to extend the lesson to include more videos per month. Have participants build a table and draw a graph. The rate of change and initial values will be easier to see.
