messages.content: The lawyer worked 50*2=<<50*2=100>>100 hours out of court
  So he worked 100+50=<<100+50=150>>150 hours total
  That means the hourly time cost 150*100=$<<150*100=15000>>15000
  Adding the upfront cost it was 15000+1000=$<<15000+1000=16000>>16000
  His brother paid half so he paid 16000/2=$<<16000/2=8000>>8000
  #### 8000
