conversations.value: Gary bought his first used car for $6,000.  Gary borrowed the money from his dad who said he could pay him back the full amount over 5 years.  Gary decided he would pay his dad back the full amount in 2 years.  How much more is Gary spending per month to pay the loan off in 2 years instead of 5?
  How to solve this?
conversations.from: assistant
conversations.value: A full year has 12 months. So 2 years is 2*12 = 24 months
  The loan amount is $6,000 that he will repay in 24 months so 6000/24 = $250 per month
  If he paid his dad back in 5 years that 5*12 = 60 months
  $6,000 loan spread out over 60 months is 6000/60 = $100 per month
  To pay it off in 2 years instead of 5, Gary is paying 250-100 = $150 more per month
