Answer:
a) $32,000
b) 9/25
c) 36%
Step-by-step explanation:
Hello!
A) How much did you save?
Let's see. In order to find the savings, we must subtract the new price from the original.
You saved $32,000 (a pretty good deal!)
B) What fraction of the original price was this?
To find the fraction, we must divide the new price from the original.
- 18,000/50,000
- 9,000/25,000 => SImplify
- 9/25 => Simplify
It's 9 twenty-fifths of the original price.
C) What fraction of the original price was this?
Convert the fraction to percent
- 9/25
- 9*4/25*4 => Denominator of 100
- 36/100
- 36%

45 +45=90
Explanation:
If your actual answer is very far from your estimate, you probably made a mistake somewhere.

<em>Additional comment</em>
50 years ago, when a slide rule was the only available calculation tool, making an estimate of the result was a required part of doing the calculation. Not only were the first one or two significant digits needed, but also the power of 10 that multiplied them. Use of a slide rule required the order of magnitude be computed separately (by hand) from the significant digits of the result.

You may also find it useful to estimate the error in your estimate. That is, you may want to know the approximate answer to 2 (or more) significant digits in order to gain confidence that your calculation is correct.
Rise over run would be your slope sooo your slope is one that what I got
