conversations.value: A store owner buys clothes wholesale and adds 80% to the wholesale price to set the retail price. The retail price of a pair of pants is $36. What is the wholesale price?

conversations.value: Let X be the wholesale price.
  The retail price of a pair of pants is X + X*80% = $36.
  Thus 1.8*X = $36.
  Thus X = $36 / 1.8 = $20.
