Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! Savings on Small Pizza = $5.95 - $5.00 = $.95 / $5.95 = 15.9663866%
Savings on Medium Pizza = $7.40 - $5.92 = $1.48 / $7.40 = 20%
Savings on Large Pizza = $8.95 - $6.98 = $1.97 / $8.95 = 22.0111732%
-----
Since you saved 15.9663866% on the small pizza, and you saved 22.0111732% on the large pizza, you saved an additional 6.0447866% on the large pizza.
-----
If the savings on the large pizza were to be identical as the savings on the small pizza on a percentage basis, then your discount on the large pizza would have been .159663866 * $8.95 = $1.428991597.
-----
Your additional savings on the large pizza over the savings on the small pizza came out to be $1.97 - $1.428991597 = $.541008403.
-----
If your savings on the small pizza were to be identical as the savings on the large pizza on a percentage basis, then your discount on the small pizza would have been .220111732 * $5.95 = $1.309664804.
-----
Your additional savings on the small pizza over what you actually received on the small pizza would have been $1.309664804 - $.95 = $.359664804.
-----
Discount was based on a percentage of the original Price.
Take the discount and divide it by the original price to get the discount rate and then multiply that by 100% to get the discount percent.
Example:
Original Price = $100.
Discount = 10
10/100 = .1 * 100% = 10%
