You can easily calculate the discount or percent-off and the final or Final Price of an item by following these steps:
79.8 times 90 divided by 100 = 79.8 × ^{90} / _{100} = 79.8 × 0.9 = 71.82 (This is the discount).
Final Price = 79.8 minus 71.82 = 79.8 - 71.82 = 7.98.
So, an item that costs 79.8, when discounted 90 percent, will have the final price equal to 7.98.
