For fundraising, the local elementary school puts on a “Jog-A-Thon” wherein students will raise money by jogging as many miles as possible and collecting donations from sponsors. At the end of the Jog-A-Thon, the top four joggers (the four that ran the most miles) will be given awards. On the day of the Jog-A-Thon, 60 kids show up to participate.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
