conversations.value: Please show me the solution for: Harold's fancy wrapping paper can wrap 5 shirt boxes or 3 XL boxes.  For the upcoming holiday, he has 20 shirt boxes to wrap and 12 XL boxes to wrap.  If each roll of wrapping paper costs $4.00 per roll, how much will he spend to wrap all of the boxes?

conversations.value: 1 roll can wrap 5 shirt boxes and he has 20 shirts boxes to wrap so he needs 20/5 = 4 rolls of wrap
  1 roll can wrap 3 XL boxes and he has 12 XL boxes to wrap so he needs 12/3 = 4 rolls or wrap
  All total he needs 4+4 = 8 rolls of wrap
  Each roll costs $4.00 and he needs 8 rolls so it will cost him 4*8 = $32.00 in wrapping paper
