conversations.value: Can you give me some step-by-step instructions for this math problem: Paddy's Confidential has 600 cans of stew required to feed 40 people. How many cans would be needed to feed 30% fewer people?
conversations.from: assistant
conversations.value: If there are 40 people, each person gets 600/40 = 15 cans.
  Thirty percent of the total number of people present is 30/100*40 = 12
  If there are 30% fewer people, the number of people who are to be fed is 40-12 = 28
  Since each person is given 15 cans, twenty-eight people will need 15*28 = 420 cans.
