Answer:
OPTION B
Step-by-step explanation:
<h2>
3a - 5</h2>
3 and 'a' are multiplied and 5 is subtracted from the result.
OPTION B says 5 less than 3 times a number would fit perfectly.
Other options talk about adding or taking ratios and clearly do not fit the case.
Hence, the right answer is Option B.
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.
