Markups and Discounts with Percents

Finding Simpler Ways You should have noticed by now that you can easily find the percent of a number using multiplication Part = (percent)whole For example 30% of 60 can be found by calculating (.3)60 = 18

Using the Strategy to Make Calculations More Efficient You can use this for discounts and markups if the original price is known Example: an item that normally cost $400 is on sale for 20% off. Because the item is 20% off, you are only paying for 80% of the item. A simple way to get the sale price is to multiply $400 by 80% or 0.8 (100% - 20% = 80%) 400(0.8) = 320

Mark ups If the original price is known, this strategy works will for markups also Example: An item that normally sells for $400 is marked up 20%. Because the item is being marked up, you are paying for more than 100% of the item. You are paying for 100% + 20% = 120% or 1.2. 400(1.2) = 480
