Gloria has $4500 saved to take a trip to Disney World Florida. The entire trip will cost her $6,375. She plans to go in 3 years. How much does she have to save each month to take
the trip to Florida?

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.
