conversations.value: Find a solution for this math problem: The dinner bill for 6 friends came to $150. Silas said he would pay for half of the bill and the remaining friends could split the rest of the bill and leave a 10% tip for the whole meal. How many dollars will one of the friends pay?
conversations.from: assistant
conversations.value: Silas paid half = 150/2 = 75
  Remaining bill paid by 5 friends = 75 + 10% of 150 = 75 + 15 = 90
  Each person will pay 1/5 which is 90/5 = 18
  Each friend will pay $18.
