conversations.value: I would love to understand how to solve this problem: Jason has a phone plan of 1000 minutes per month. Every day he has a 15-minute call with his boss, and he's had 300 extra minutes of call this month to other people. How many minutes does Jason have left if this month has 30 days?
  Can you explain?
conversations.from: assistant
conversations.value: First find the total time Jason spends calling his boss: 15 minutes/call * 30 calls/month = 450 minutes
  Then subtract the minutes Jason has already used to find how many he has left: 1000 minutes - 450 minutes - 300 minutes = 250 minutes
