Question

A girl scout troop sold cookies. If the girls sold 5 more boxes the second week than they did the first, and if they doubled the sales of the second week for the third week to sell a total of 431 boxes of cookies, how many did they sell each week?

Answer 1

You will have 4 times the second week amount of cookies, minus 5 (of the first week), in total

so first week 104, second 109, third 218

Answer 3

let the no. of boxes sold in first week x
in second week x+5
in third week 2(x+5)=2x+10
total boxes sold=431
x+x+5+2x+10=431
4x=416
x=104
so in first week 104 boxes sold
in second 109
in third 218

Answer 4
