An item on sale costs 25% of the original price. If the original price was $20, what is the sale price?

So an additional discount of 50% off the sale price would bringthe price to 35% (that is, 50% • 70%) of the original price. Thus, a $100item would cost $35 after both discounts. An 80% off sale means thatyou pay 100% - 80%, or 20% of the original cost of the item.

20x25%=5

the sale price is $5
