$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.
42 because 56 mines 14 equals 42
The answer is 65 if your wondering why you have to put the numbers from least to greatest then find the one that is in the middle
