At a school fundraiser for every 9 boxes of chocolate sold, you even 6 points ,If you were to sell 18 boxes, how many points would you have earned

Question

Help me and show me how u did it

Answer 1

You can set up a proportion for this problem. Let x = number of points you earn for 18 boxes. Then:

 

points earned/boxes of chocolates = points earned/boxes of chocolates

6/9 = x/18

 

Now, cross-multiply to solve for x:

 

6(18) = 9x

108 = 9x

12 = x

 

You will earn x = 12 points.

 

 

 

You could also solve this by noticing that 18 boxes is two sets of 9 boxes. So, you'll earn 6 points twice, for a total of 12 points.
