conversations.value: Mrs. Smith wanted to buy wears worth $500. She went to a boutique with the $500 but by the time she had picked out everything she liked, she realized that she would need two-fifths more money than she had. If the shop owner gave her a discount of 15%, how much more money will she still need?
  Work out the solution step by step.

conversations.value: Two fifths of $500 is (2/5)*$500 = $200
  She needed $200 more than $500 which is $200+ $500 = $700
  15% of $700 is (15/100)*$700 = $105
  She was given a $105 discount so she has to pay $700-$105 = $595
  She would still need $595-$500= $95
