Employees at a clothing store recieve 20% discounts on what they purchase at that store. How much will an employer save on a $450 suit?

Easiest way to work it out is to divide by ten, that gives 10% of your original number. Multiply that by two to get 20% and minus that from the original number to get the discount.

450/10 = 45 which is 10% of 450.

20% of 450 = 10% x 2 or 45 x 2

therefor 20% of 450 is 90.

450-90 = the discount the shoppers recieve.
