Discount = Original Price × Discount % / 100

Discount = 109.00 × 20/100

Discount = 109.00 × 0.20

You save = $21.80

You can easily calculate the discount or percent-off and the final or Final Price of an item by following these steps:

1. Multiply the original price by the discount percentage, then divide it by 100 :

109.00 times 20 divided by 100 =

109.00 × 20 / 100 = 109.00 × 0.20 = 21.80 (This is the discount).

2. Subtract the discount (percent-off) from the original price to get the final price:

109.00 minus 21.80 = 109.00 - 21.80 = 87.20.

So, an item that costs 109.00, when discounted 20 percent, will have the final price equal to 87.20.
