Question

Will medal! Please

Joshua paid $28 for a pair of shoes that has been discounted 20%. What is the original price of the shoes before the discount?
a) Set up an equation using the discounted price of the shoes and the percentage of the discount.








b) Solve the equation.

Answer 1

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$

Answer 2

where did you get .75 from?

Answer 3

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

Answer 4

sorry I'm really confused..

Answer 5

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?
