Paige bought a handbag for $49.75. Nevaeh spent 2.5 times more on her handbag, while Naomi spent 3.5 times more than Paige on her handbag. How much total money was spent on the three handbags?

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°

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.
