Here's an example: Jamie makes $8.95 per hour. He's such a good worker that his boss gives him a 25 percent raise. How much per hour does Jamie make now?

To find the dollar amount of the raise, multiply Jamie's previous salary by the decimal equivalent of 25 percent:

Round this number up to $2.24, just to make Jamie smile. Now add the raise to Jamie's original salary: $8.95 + $2.24 = $11.19.

Let's try another one: Katie is very excited. For only $45, she bought a set of towels that usually sells for $60. What was the percentage of her discount?

Divide the new price by the original price:

The new price is 75 percent of the original price, which means Katie's discount was 25 percent.
