Assuming we need to find out what 20% off of the prices listed is, we can set up equations for each of them, where x is the original price.

New price = or simplified to

So, putting the original prices through the formula, we get these values:

$15 --> $12
$12 --> $9.60
$25 --> $20
$120 --> $96
$35 --> $28
$28 --> $22.40
