The new price of an item is 25 percent higher than the old price of 8800. The old price is what percent lower than the new price?

The first question is what is 25 percent of 8800? We write: 0.25.8800=2200

The new price is: 8800+2200=11000

Now, we have to ask 2200 is what percent of 11000. We write: 2200=x/100(11000)=20 percent lower.
