conversations.value: Explain how to solve this math problem: John collects garbage from 3 different apartment complexes.  The first two have 200 apartments each and the last one is 60% bigger than the other two combined.  He collects garbage 3 times a week from each place and he gets paid $.40 per collection for each apartment.  How much money does he make in a week?

conversations.value: The first two complexes have 200+200=400 apartments
  The third one has 400*.6=240 more apartments than those 2 combined
  So in total, it has 400+240=640 apartments
  So he goes to 640+400=1040 apartments each time
  That means he visits 1040*3=3120 apartments every week
  So he makes 3120*$0.4=$1248 every week
