An item is regularly priced at $40. Lena bought it at a discount of 60% off the regular price. How much did Lena pay?

So the original price is 40 dollars. We can see how much she saved by multiplying the original amount with the discount. 40 x. 60=24. So she saved 24 dollars. We can then subtract 24 from 40 to get a price of 16 dollars.
