conversations.value: If Benny had twenty red balloons in the bundle, and he threw two pieces of bologna at each red balloon, then he threw 2*20=40 pieces of bologna at red balloons in the bundle.
  If he threw a total of 58 pieces of bologna at balloons in the bundle, then he threw 58-40=18 pieces of bologna at yellow balloons.
  If he threw three pieces of bologna at each yellow balloon, then he had 18/3=6 yellow balloons.
