What is the percentage?

  • A percentage (from Latin per centum "by a hundred") is a number or ratio stated as a fraction of 100 in mathematics.
  • It is frequently symbolized with the percent sign, " percent ".
  • A % is a dimensionless (pure) number; it does not have a unit of measurement.

To find about how many people would likely donate:

First, find 80 is what percent of 200.

∴  [tex]\frac{80}{200} * 100 = 40%[/tex]

So, 80 is 40% of 200.

Centreville population is 9,800.

Now, take out 40% of 9,800.

[tex]\frac{x}{9,800} *100 = 40\\\frac{x}{98} =40\\98*40 = 3,920[/tex]

Therefore, (C) 3,920 people would likely donate.
