$312.49 ; here's how: You have original price is 100%, final price = original price - discount amount, and discount amount = original price * discount percent.So Final price = original price - original price * discount percent = (Original price)*(100 % - discount percent).249.99 = P0 * (100%-20%) = P0 * (0.80) ---> P0 = 249.99 / 0.80 = 312.4875
The final result is 10.4% more than the original number.
% change = (final # - original #)/original# * 100%(140-80)/80 * 100% = 75% increase
For Percent Off, calculate the 60% on the original amount. This is the amount of the discount. Then subtract from the original, to get the final price. Or you can do (100% - discount%) then multiply that by the original, to get the final. So in this case: 100% - 60% = 40%. So multiply 0.40 x 82 = 32.80
