Question

Stephanie, Amanda, and Alison are selling Girl Scout Cookies. Stephanie sold three times as many boxes of cookies as Alison. Amanda sold two less than four times as many boxes of cookies as Alison. The three girls sold a total of 190 boxes. How many boxes did each girl sell?

Answer 1

Let x be the number of boxes sold by Alison, 3x be the number of boxes sold by Stephanie
and 4x-2 be the number of boxes sold by Amanda

(x) + (3x) + (4x-2) = 190
8x + -2 = 190
8x = 192
x= 24

Alison: 24 boxes
Stephanie: 72 boxes
Amanda: 94 boxes
