conversations.value: Tim sleeps 6 hours per day for 5 days a week and 10 hours a day for the other 2.  How much total sleep does he get?
  Can you solve this problem?
conversations.from: assistant
conversations.value: He gets 6*5=30 hours of sleep on 5 days
  He gets 10*2=20 hours the other days
  So he got 30+20=50 hours
