Answer 1

Hello! In this problem you need to first establish that Meili + Kaitlyn = 160; Let's put that M means number of stickers of Meili and K is number of stickers of Kaitlyn. We know that Meili has 3 times as many stickers as Kaitlin; mathematically this can be expressed as M = 3K; Now you plug into the equation: K + 3K = 160  *they can be added because they are the same variable; 4K = 160; 160/4 = k; k = 40. So K has 40 stickers and Melie has 3 times as many stickers as her. this means that M = 3(40); M = 120 and K = 40. To check this answer just make sure that 120 = 3(40); and that 120 + 40 = 160. I hope this helps! Let me know if you have any other question.
