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?

Question

anonymous · Answer

Week3 = 2*Week2
Week2 = Week1 + 5
Week3 + Week2 + Week1 = 431

Try to rewrite the third equation so that it only has (week1) in it.

(seeing as others have probably already got this one covered)  I like the cookies :-3

First step to such word problems is to represent your unknown values, for instance, you can let

x = how many boxes they sold the first week.

If that were so, how would you represent the sales for the second and third week? :)
