conversations.value: Please show me the solution for: Erica made 20 Valentine's cards to pass out.  Her dad brought her 2 boxes of pre-made Valentine's cards that had 15 cards each.  She passed out 24 to her classmates, 5 to her family and received 17 from family and friends.  How many Valentine's Day cards does Erica now have?

conversations.value: Her dad gave her 2 boxes of 15 cards so 2*15 = 30
  She made 20, was given 30 and received 17 so 20+30+17 = 67 cards
  She passed out 24 and gave 5 cards to family and friends so she gave away 24+5 = 29 cards
  She had 67 cards and gave away 29 cards so 67-29 = 38 cards left
