You are researching the price of MP3 players. You found an average price of $58.80. One MP3 player costs $56 and another cost $62. Write and solve an equation to find the price of the third MP3 player.

Divide 40%5 and your answer is 8

Understanding what? lol

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.
