decimals and percents

Period 3

Definition

• A percentage / fraction off a regular price.

Example Examples of a discount of 25% is:

$46.25 * .25 = $11.56 (Discount) Discounted Price = $34.69 [46.25 – 11.56] $18.36 * .25 = $4.59 (Discount) Discounted Price = $13.77 [18.36 – 4.59]]

• Multiply the original cost by the percent (%) of the discount.

• To figure out the discounted price you subtract discount amount from the regular price.
