In this problem, we are investigating how the time constant affects the shape of a graph.
Remaining candies (C) = candies present (C0) - (10/100)C0
At t = 0, C0 = 1000.
At t = 1h, C1 = 1000 - (10/100)(1000) = 900
At t = 2h, C2 = 900 - (10/100)(900) = 810
At t = 3h, C3 = 810 - (10/100)(810) = 729
At t = 4h, C4 = 729 - (10/100)(729) = 656.1
a. Consider a candy jar, initially with 1000 candies. You walk past it once each hour. Since you don't want anyone to notice that you're taking candy, each time you take just 10% of the candies remaining in the jar. Sketch a graph of the number of candies remaining as a function of time.
b. How would the graph change if instead of removing 10% of the candies, you removed 20%? Sketch a new graph.
