How much do I have to pay if I buy something that cost $25 and has a 10% off?

If you would like to know how much will you have to pay after reduction, you can calculate this using the following steps:

10% of $25 is x

10% * 25 = x

x = 10/100 * 25

x = $2.5

$25 - $2.5 = $22.5

The correct result would be $22.5.
