please show me step by step

anonymous · Answer

what is 20% of $28?

anonymous · Answer

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

then you move the decimal to the left

anonymous · Answer

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

anonymous · Answer

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