Henry was buying clothing for the fall at good stuff. he spent $59 on a pair of jeans, $45.87 on a shirt , and $121.39 on a pair of shoes. how much did he spend?

59 + 45.87 + 121.39 = $ 226.26 <==

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.
