Perhaps a little difficult to explain.
Take for example:
Computer good were sold at 35% profit of the original price. The goods cost $500. What was the original price of the goods?

Goods = 100%.
Profit = 35%.
Goods + Profit = 135%, and this cost $500.
135% = $500. (÷ 135).
1% = $3∙703703.... ( x 100)
100% = $ 370∙37

Also, Profit = Selling price - Whole sale price = $500 - $ 370∙37 = $126∙62...

I'm not sure what you mean by " proginal" but it muse be either the final or the original price you seek.

A percentage is another way or expressing 100Th's of something.

So 25% can be expressed as .25
20% can be expressed as .20 or .2
50% is .5


Original price - Origionalprice X discount % = Finalprice

Example Item cost $10.50 normally
Take 20% off

$10.5 - $10.5 X 20%
=$10.5 - $10.5 x .20 (note you must multiply before subtracting!)
=10.5 - 2.10
= $8.4

Here is an Easier Alternate METHOD!

Original price * ( 1-discount % )= Finalprice
10.5 x (1-.2)= final price
10.5 x .8 = final price
8.4 = final price




NOW lets do this the opposite way --
Something is marked down to be sold at $8.40
a 20 % Discount was applied ...

what was the Original price?
Original price * ( 1-discount % )= Finalprice

O x (1 - D )= F

O x (1 - .20 )= $8.4
O x .8 = 8.4
O= 8.4 / .8
O = 10.5

division divide the new price by the discount like 37.5 divided by .75 = 50--------37.5 new price discount was 75% (.75) old price was 50 the formula is not easy to write with no math symbals but as a fraction the new price on top discount on bottom =old price
