Find Original Price

What is the best way to find the original price of an item?

Sample:

 

original price - discount= sales price

original price is x
sales price is $59.50
discount is 30% of x =>0.30x


x-0.30x=59.50
0.70x=59.50
x=59.50/0.70
x=85.00
original price is $85.00

 

Thank you. Do you realize how many people go shopping every passing day and have no clue how to find the original price of items after a discount? I can't count that high, honestly.

 

Why would people want or need to know the original price? All they are concerned with is the current price compared to the perceived value of the item.

 

True in real life but in the world of math it is a legit thread.
