conversations.value: I need a clearer understanding of how to solve: Olivia bought two packs of basketball cards at $3 each, and 5 decks of baseball cards at $4 each.  If she had one $50 bill, how much change did she receive?

conversations.value: Two packs of basketball cards cost 2 x $3 = $6.
  Five decks of baseball cards cost 5 x $4= $20.
  Thus, the total cost of the cards was $6 + $20 = $26.
  Therefore, Olivia received change of $50 - $26 = $24.
