conversations.value: Find the answer to this math problem: John needs to take 2 pills a day.  One pill costs $1.5.  The insurance covers 40% of the cost.  How much does he pay in a 30-day month?
conversations.from: assistant
conversations.value: It cost 2*1.5=$3 a day.
  So it cost 3*30=$90 per day.
  Insurance covers 90*.4=$36.
  So he pays 90-36=$54 a month.
