Anyone good at math?

I'm trying to help my wife with a problem at work. She needs to know like say something costs $50, but it's been marked up 22% from the original price. What is the formula to figure out what the original price was? That isn't just taking 22% from 50, which is easy to do, but 22% of the orignal price.

 

X being the original price, X*1.22=50 or 50/1.22=X

 

Thank you very much!

I was doing it the hard way, times the original price by .22 and then adding that to the original price and then trying to figure out how to go backwards from that. Your way is much simpler.
