You buy jeans that cost $42.00 (price before the sale). They are on sale for 45% off. How much will you pay with the sale? *

$23.10

Step-by-step explanation:

First, convert the 45% to a real mathematical number. For percents, this is always done by dividing the 45% by 100%, or 45% / 100% = 0.450.

Second, find out what 45% of $42 is. This is the amount of the sale discount. This is always found by mulitplying 0.450 by the item's cost $42, like this:

0.450 x $42 = $18.90.

So for this sale, you'll save $18.90 on this item.

This means, the cost of the item to you is

$42 - $18.90 = $23.10.
