Finding discount % given original price and discount value?

Question

I want to know given the original price and discount value how can i find the discount percentage e.g

SUB-TOTAL:  $209,055.00
One -Time Special Discount  : -$38,000.00
Grand Total :   $171,055.00

Answer 1

Anytime you are talking about discounted prices you can use the following equations to find either the original amount, new price, discount amount, or discount percentage:

equation 1: original amount - discount amount = new amount equation 2: discount amount = (original amount) * ( the decimal form of percent discount)

Since we know the discount amount and the original amount then we can use equation 2 to solve for the decimal form of the percent discount. You can then change this into a percentage by moving the decimal place two to the left (same as multiplying by 100).
