**Eddie: $72000/(14yr*12mo)=428.6$/mo+428.6$*(4.7%)/100%
Eddie pays 428.6$/mo+20.14$/mo. If he pays off his loan 6 years earlier he would save: $20.14*6yr*12mo= $1450.08
**Lee: $92000/(14yr*12mo)=547.62$/mo+547.62$*(4.7%)/100%
Lee pays 547.62$/mo+25.74$/mo. If he pays off his loan 6 years earlier he would save: $25.74*6yr*12mo=$1853.28
So its A. <span>Lee would save more, since he has $20,000 more in principal.</span>

A ratio is a mathematical comparison of two numbers, based on division. For example, suppose you bring 2 scarves and 3 caps with you on a ski vacation. Here are a few ways to express the ratio of scarves to caps
![2:3 \: \: \: \: 2 \: to \: 3 \: \: \frac{2}{3}](https://tex.z-dn.net/?f=2%3A3%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%202%20%5C%3A%20to%20%5C%3A%203%20%5C%3A%20%20%5C%3A%20%20%5Cfrac%7B2%7D%7B3%7D%20)
The simplest way to work with a ratio is to turn it into a fraction. Be sure to keep the order the same: The first number goes on top of the fraction, and the second number goes on the bottom.
In practice, a ratio is most useful when used to set up a proportion — that is, an equation involving two ratios. Typically, a proportion looks like a word equation, as follows:
![\frac{scarves}{caps} = \frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bscarves%7D%7Bcaps%7D%20%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20)
For example, suppose you know that both you and your friend Andrew brought the same proportion of scarves to caps. If you also know that Andrew brought 8 scarves, you can use this proportion to find out how many caps he brought. Just increase the terms of the fraction
![\frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20)
<h2> </h2>
so that the numerator becomes 8. Do this in two steps:
![\frac{scarves}{caps} = \frac{2 \times 4}{3 \times 4} \\ \\ \frac{scarves}{caps} = \frac{8}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bscarves%7D%7Bcaps%7D%20%20%3D%20%20%5Cfrac%7B2%20%5Ctimes%204%7D%7B3%20%5Ctimes%204%7D%20%20%20%5C%5C%20%20%20%5C%5C%20%5Cfrac%7Bscarves%7D%7Bcaps%7D%20%20%3D%20%20%5Cfrac%7B8%7D%7B12%7D%20)
As you can see, the ratio 8:12 is equivalent to the ratio 2:3 because the fractions
![\frac{2}{3} \: \: and \: \: \frac{8}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20%20%5C%3A%20%20%5C%3A%20and%20%5C%3A%20%20%5C%3A%20%20%20%5Cfrac%7B8%7D%7B12%7D%20)
are equal. Therefore, Andrew brought 12 caps

<u>Understanding:</u>
The sum of 3 times a number (i'll define it as x) and 4 means
is between -8 and 10 which means the value of 3x+4 is less than 10 and greater than -8. With that said, the inequality for that problem would be
.
<u>Solving the problem:</u>
Now we know that
, you can solve the problem by <em>subtracting 4</em> from each side then<em> dividing by 3.</em>
