QUESTION 9 of 10: Last year your store earned $200,000. The latest trend report states that fashion industry sales will increase by 15% annually for the next 2 years. What is your predicted sales in 2 years?

230,000
264,500
310,000
330,000

200000 * 1.15 * 1.15 = 264500

Do you have answer choices?

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.
