Which sale gives the greatest percent discount? 20% off the original price. 75% of the original price. Original price reduced by 30%. It depends on the original price.

75% off the original price

Step-by-step explanation:

No it doesn't depend on the original price. Why, because when it says original price reduced by 30%, that basically means 30% off the original price. Let's say the original price is $100, okay 20% off the original price is only $20 off, 75% off of the original price is $75 off, and to have the original price reduced by 30% means the price goes from 100 to 70, but the price would be $25 in this case after getting 75% off.
