conversations.value: Three times the sum of marbles that Atticus, Jensen, and Cruz have is equal to 60, meaning together they have 60/3=20 marbles.
  If Atticus has half as many marbles as Jensen, and Atticus has four marbles, Jensen has 2*4=8 marbles.
  Together, Atticus and Jensen have 8+4=12 marbles.
  Since the sum of marbles that Atticus, Jensen, and Cruz have is equal to 20, and Atticus and Jensen have 12 marbles, Cruz has 20-12=8 marbles.
