conversations.value: Find the answer to the math problem: Marcus wants to buy a new pair of shoes. He decided to pay not more than $130 for them. He found a pair for $120, on which he got a discount of 30%. How much money will he manage to save by buying these shoes and not spending the assumed maximum amount?

conversations.value: The discount on the shoes Marcus found is 120 * 30/100 = $36.
  That means he only had to pay 120 - 36 = $84.
  So Marcus was able to save 130 - 84 = $46.
