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:

    100 times 30 divided by 100 = 100 × 30 / 100 = 100 x 0.3 = 30 (This is the discount).

  2. Subtract the discount (percent-off) from the original price to get the final price:
  3. Final Price = 100 minus 30 = 100 - 30 = 70.

So, an item that costs 100, when discounted 30 percent, will have the final price equal to 70.
