conversations.value: Break down this math problem: John has to hire a lawyer.  He pays $1000 upfront.  He then gets charged $100 per hour.  The lawyer has to work 50 hours in court time.  It takes 2 times that long in prep time.  His brother pays half the fee.  How much did John pay?
conversations.from: assistant
conversations.value: The lawyer worked 50*2=100 hours out of court
  So he worked 100+50=150 hours total
  That means the hourly time cost 150*100=$15000
  Adding the upfront cost it was 15000+1000=$16000
  His brother paid half so he paid 16000/2=$8000
