Question 769716: A backpack is on sale at a discount of 35%. The sale price is $31.20. find the original price of the backpack. Answer by fcabanski(1391) (Show Source):
You can put this solution on YOUR website! To find the final sale price use the formula O(1-d)=s. Where O is original price, d is discount % (the given % divided by 100) and s is the sales price.
O(1-.35)=31.20 so O = 31.20/(1-.35) = 31.20/.65 = $48.
