Start by converting the percentage into a decimal. From there, you should be able to set up an equation where 

original price x discount = discounted price

and solve for the original price. 

eg: If you bought an item that was regularly 20$, and it was 25% off : 

20$ * 0.75 = 15$

where did you get .75 from?

wilsondanielle · Answer

0.75 is 75% - if it's 25% off, you pay 75% of the original price.

sorry I'm really confused..

wilsondanielle · Answer

that's ok!

So 100% of the original price is the original price. If you're taking 25% off the original price, then what you pay will be (100-25)% of the original price - which is 75%. If it's 5% off, you will pay (100-5)% - 95%, and so on so forth. 

in your example, it's 20% off. What is the portion of the original price you will pay?
