I found out this answer by simply dividing $51 by 3 because it is 75% of the original price and 75 is 3 quarters of a whole. When I did this, I got the number 17. 17 is the other 25% that got taken off the original price. To find the original price at this point, you just want to add 51 and 17 to get you the number 68. The original price was $68
