Joyas Birthday Problem

• Joya's mother says
• Last year we spent 60 on your birthday party.
  We can only afford to spend that same amount
  again this year. Last year you had 12 friends
  over for ice cream, birthday cake, and games.
  That cost 5 for each person.

• If we go to Palermos Pizza it will cost 10 for
  each person. In that case, you will only be able
  to take 6 friends. Or, for the same 60, you can
  have 12 friends over for ice- cream, cake, and
  games. It's your choice."
