messages.content: He sold 1,000,000-100,000=<<1000000-100000=900000>>900,000 not counting the advance
  So he made 900,000*2=$<<900000*2=1800000>>1,800,000 from selling the books
  His agent took 1,800,000*.1=$<<1800000*.1=180000>>180,000
  That means he kept 1,800,000-180,000=$<<1800000-180000=1620000>>1,620,000
  #### 1620000
