they give you 116 candy bars in 2 hours and 198 candy bars in 3 hours
they say time is x so the ordered pairs would be (2,116) and (3,198)
using the ordered pairs you can find the slope
y2-y1 / x2-x1 =
198 - 116 / 3-2 = 82/1
m=82
y intercept = 82*2 +b =116 = 164 +b =116 b = 116 - 164 = -48
y = 82x-48
when x = 5
y = 82(5) -48 = 362 candy bars sold in 5 hours
