Agirl scout troop sold cookies. if the girls sold 5 more boxes the second week than they did the first, and if they double 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?

Boxes sold first week = 104

Boxes sold second week =x+5= 104+5=109

Boxes sold third  week = 109 times 2= 218

Step-by-step explanation:

Let x be the number of boxes sold in first week

the girls sold 5 more boxes the second week

So number of boxes sold in second week is x+5

they double the sales of the second week for the third week

So number of boxes sold in third week is 2 (x+5)

Total boxes sold is 431

subtract 15 from both sides

divide by 4 on both sides

Boxes sold first week = 104

Boxes sold second week =x+5= 104+5=109

Boxes sold third  week = 104 times 2= 218

it is a reproduction.
