    If the book regularly sells for $28 this is 100% price but it is 20% off 100%- 20% = 80% is the price of the book now 80% times $28 gives you the price after discount

    No. 80%/ 100%= .08 .08* 28= 22.4

    Just like Dez said, 100%= 28, and you know 20%=5.6 28-5.6= 22.4. Different method, but same answer.
