A botanist uses the representations below to show the heights in inches, h, of different plants over a period of time, t.
Time in weeks, t
Height in inches, h
h = StartFraction 4 t Over 3 EndFraction
A graph has time (in weeks) on the x-axis and height (in inches) on the y-axis. A line goes through points (50, 150) and (120, 360).
If the growth patterns continue, how much taller is the tallest plant than the shortest plant at 120 weeks of growth?
