Eating Two-Variable Linear and Exponential Equations: Tutorial 43
Activity
Suppose a scientist is watching a video that models the growth of bacteria. He is taking screen shots of the video after
every second of "video time," with each second of video time correlating to 20 minutes of "real time." In the video, each
bacteria cell splits into two cells with each passing second, as seen in the images from the video. In these screenshots, t is
the video time in seconds.
