Find the original price of a pair of shoes if the sale price is $ 15 after a 75% discount.

Question

I need help solving problems like this

Answer 1

Another way to approach this problem is to ask,

 

15 is 25% of what number? (because 100 - 75 = 25. Full price is 100%, so we subtract the discount percentage from the whole price percentage to get the sale percentage)

 

Let x = the number.

 

15 = 0.25x

1500 = 25x

60 = x

 

The original price was $60.
