Question

find the original price of a pair of shoes if the sale price is $63 after a 30% discount

Answer 1

The original unknown price was 100%.
If the discount was 30%, that means you are paying 70% of the price, right?

Answer 2

\[.7x=63\]
solve for x

Answer 3

I'm just going off of what mathstudent said. You're only paying 70% or .7 of the original unknown value, which I wrote as x, so you end up paying 63 dollars.
