    it's only 20% IF the total price for the three items was $100

    you save $20. This is the discount divide the discount by the original price to get 20/60 = 1/3 = 0.3333... = 33.33%

    the discount as a fixed number is $20 the discount as a percentage (of the original price) is roughly 33% the idea is that you take 33% of the original price ($60) and subtract that off the original price
