If you are looking for a percentage of a monetary amount, you need to multiply the $ amount by the % amount.

$8.49 x 5%

We need to have our % in decimal form, so move the decimal 2 places to the left.

$8.49 x 0.05 = x

After you get x, subtract that from your regular price to determine the sale price.

If you have a regular price of $8.49 with a 5% discount what you need to do is find out what 5% of 8.49 is. This is a simple ratio of 5/100=x (the disount amount)/8.49.

So cross multiply and you get 5 x 8.49=100x

Simplify algebraicly and you get a final answer of .4245. Round down and your final discount is .42 cents.

Regular price: $8.49

Discount: 5%

First note that 5% (% = per cent) means 5 parts out of 100 parts, or 5 cents out of 100 cents. So to find the decimal form of the the discount, divide 5% by 100%. That is,

5%/100% = 0.05

Therefore, to find a 5% discount on an item with an original price of $8.49 (i.e., 5% of 8.49), multiply the price of the item by the decimal form of this percentage. That is,

8.49(5%/100%) = 8.49(0.05) = 0.4245 ≈ 0.42

The sale price is thus found by subtracting the discount value from the original price:

8.49 - 8.49(5%/100%) = 8.49 - 8.49(0.05) = 8.49 - 0.4245 = 8.0655 ≈ 8.07

or, 8.49 - 0.42 = 8.07

Thus, 5% of an item regularly priced at $8.49 is $0.42. With this, the sale price of the item is $8.07.
