Amy Paid 63.75 For A Pair Of Running Shoes During A 15% Off Sale.what Was The Original Price?

Original price * (1-percentage of sale )= discount/current price

original price = (current price)/(1-percentage of sale )

here
original price = x

current price = 63.75
percentage of sale =15%

x = 63.75/(1-.15)

x= 63.75/.85

x= 75

So original price = 75
