Answer:
12
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.
Answer:
x = 11
x = 7
Step-by-step explanation:
divide each side by 3 to get:
(x-4)² = 9
(x-4)² is the difference of two squares and has these factors:
(x+2)(x-2) = 9
x + 2 = 9; x = 7
x - 2 = 9; x = 11
Pretty sure the answer is 2
