An item is regularly priced at $60 . Jessica bought it on sale for 65% off the regular price. How much did Jessica pay?

adoni [48]

First, convert the 65% to a real mathematical number. For percents, this is always done by dividing the 65% by 100%, or 65% / 100% = 0.650.

Second, find out what 65% of $60 is. This is the amount of the sale discount. This is always found by mulitplying 0.650 by the item's cost $60, like this:

0.650 x $60 = $39.00.

So for this sale, you'll save $39.00 on this item.

This means, the cost of the item to you is

$60 - $39.00 = $21.00.
