A girl scout sells 3 boxes of cookies during week 1. She has a goal to sell twice as many cookies each week as she did the week before. If she succeeds in doing this during weeks 2, 3, 4, and 5, how many boxes will she sell all together? a0

• lcrockclimber: Week Two: 6 Boxes
  Week Three: 12 Boxes
  Week Four: 24 Boxes
  Week Five: 48 Boxes
  
  Final Answer: 96 Boxes
  (Add them all together)
• amiobidova: If she wants to double the number of cookies she sells, then you just multiply by 2.
  
  Week 1: 3 cookies
  Week 2: 6 cookies
  Week 3: 12 cookies
  Week 4: 24 cookies
  Week 5: 48 cookies
  
  3+6+12+24+48 = 93. 
  
  All together, she sold 93 cookies. 
  
  Hope this helped! :)
