Question 523363

  Let the purchase price = 100
  Tax @ 8%              +=   8
  Total purchase price:    108

  If 108%  =  $ 30.24
  then 100% =    {{{((30.24)/(108))*100 = 3024/108 = 28}}}

  So the purchase price = $28 (discounted price);

  Let the original price = 100
  Discount @ 20%       (-)  20 
  So discounted price    =  80

  If 80%    =    $28
  So the original price:  {{{((28)/80)*100 = 2800/80 = 35}}}

  So the original price = $35  Answer.    I hope you have understand this. All the best.
