75% OFF!
ICE Princess25 [194]
$676.

If the sale price of the coat is $169, you are looking for the original price. I like to think about it in the sense that if an item is 75% off, you are paying 25% of the original amount. Using that logic, in order to determine the sale price you would use the equation

Original price * 25% = $169

To solve for the original price:

Original price = $169/.25 = $676.
