Abracadabra has four different coins with values as shown at the right. Suppose you had just one of each of the four different coins. How many different amounts can be made using one or more of the four different coins?

Whose mistake? can you give more details to what the question is asking?

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.
