You have $28, and you want to get half-dollar coins from the bank to give to children who come into your store. what is the most you can get?

E, 56, because you have 28 dollars, and you have to multiply that by two to get half dollars. 28*2=56.

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.
