Percent Change = New Value − Old Value|Old Value| × 100%
Example: There were 200 customers yesterday, and 240 today:
240 − 200|200|× 100% = 40200 × 100% = 20%
A 20% increase.
Percent Error = |Approximate Value − Exact Value||Exact Value| × 100%
Example: I thought 70 people would turn up to the concert, but in fact 80 did!
|70 − 80||80| × 100% = 1080 × 100% = 12.5%
I was in error by 12.5%
(Without using the absolute value, the error is −12.5%, meaning I under-estimated the value)
The difference between the two is that one states factual calculations and the other is a theoretical guess
<span><span>1.
</span>The restaurant is making 22 ¾ cups of chowder.
Each cup of chowder holds 7/8 of a cup.
Then the restaurant charges 2.95 dollars per bowl. Let’s find out how much
money will the restaurant earned.
Solutions:
=> 22 ¾ = 22.75 cups of chowder
=> 7/8 = 0.88 cup of chowder it can holds.
Let’s solve to get the correct answer:
=> 22.75 / .88 = 25.85 cups in all.
Then, let’s multiply this with the amount
=> 25.85 * 2.95 = 76.26 dollars.
SO the restaurant earned 76.26 dollars for the chowder.</span>
