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.

The linear equation represents y = mx + b describes several real world situations such as
- Relation between printer and ink cartridges,
- Relationship between number of songs and how much is left on the card.
<u>Step-by-step explanation</u>:
Linear equations y = mx + b.
m is your rate of change.
b is your constant. This is the initial value of y. The value of y when x is 0.
Finally, y is the thing that depends on x.
Oh right, examples:
- I buy a printer for $100 and the ink cartridges cost $25 each. The relationship between ink cartridges and total cost.
total cost = 25(cartridges I buy) + 100 or y = 25x + 100
-
I get a $100 iTunes gift card for my birthday and then start buying $1 songs. The relationship between the number of songs I buy and how much is left on the card
amount left on card = -$1(songs bought) + 100 or y = -x +100
The absolute value equation written by Edwin according to his intention in the task content is; |x -3.9| = 0.3 and The values that are 0.3unuts from 3.9 are; 4.2 and 3.6.
<h3>What absolute value equation can be written by Edwin to find the numbers which are 0.3 units away from 3.9 on the number line?</h3>
Since the numbers in discuss are required to be 0.3 units from 3.9, it follows that one number is greater while the other is less than 3.9 and hence the required absolute value equation is;
|x -3.9| = 0.3. which can be solved as;
x-3.9 = 0.3; x =4.2.
Or
x -3.9 = -0.3; x = 3.6.
