So you know the marked down price is $79.26, after a 35% sale. To find the original price is quite simple:

Let's start off with ??? being the orignal price in dollars.

We know that   ??? - (??? x 0.35) = $79.26
   Original Price ^       ^ Discount of 35% in dollars

Pretend ???? is just another variable.
??? - (0.35???) = $79.26          
          0.65??? = $79.26
                 ??? = $121.94

Therefore the original price is $121.94.

To check:

 $121.94 - ($121.94 x 0.35) = $79.26
