An item is regularly priced at $40. she bought it at a discount of 35% off the regular price. How much did she pay?

She payed $25 (not including tax). To work this problem, you need to set up a ratio.

x 35

- - = - -

40 100

This will show you how much money is off of the item.

After you solve the ratio (cross multiply and divide), you should have gotten the answer $14. Then you subtract 14 from 40 to get the price of the item currently at 35% off. The answer would be $25.
