Meghan had to go to the grocery store and pick up 1 gallon of milk ($2.55), 2 dozen eggs (1 dozen $1.25), a loaf of bread ($2.99), and 2 boxes of grits (a box $1. 76). She only had $20 on her to spend. Will Meghan have enough money to cover her grocery items? Explain the steps that you took to solve this problem.

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.
