A group of friends wants to go to the amusement park. They have $131.25 to spend on parking and admission. Parking is $16.25, and tickets cost $23 per person, including
tax. Write and solve an equation which can be used to determine p, the number of
people who can go to the amusement park.

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.
