#9 - The Question

Answer:

Step-by-step explanation:

There are many ways to approach this problem. I like a method that uses the least amount of computation. We could figure how much Wendy makes on a bag of chips, the additional amount Wendy wants to make, then divide the latter by the former to find the number of additional bags to sell.

We could use a proportion to figure the number of bags corresponding to $126 in earnings, then subtract the 72 bags already sold. Essentially, we will do this, but without the intermediate numbers.

The additional fraction of 72 bags will be ...

(126/108) -1 = 18/108 = 1/6

Then Wendy must sell an additional ...

(1/6)×(72 bags) = 12 bags

to increase her earnings to $126.
