LaToya has a job offer in which she will receive $475 per month in addition to a commission of 3.5 percent of her total sales amount. In her current job, she earns $925 per month in addition to 1.25 percent commission. How much must she sell per month in order to make the new job a better financial option for her?

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.
