conversations.value: Jane is trying to decide whether to buy a house or a trailer. A house costs $480,000 and a trailer costs $120,000. Each loan will be paid in monthly installments over 20 years. How much more is the monthly payment on the house compared to the trailer?
  Give me a detailed solution.

conversations.value: First find how many months the loans last: 20 years * 12 months/year = 240 months
  Then divide the cost of the house by the number of payments to find the monthly payment before interest: $480,000 / 240 months = $2000/month
  Then do the same thing to find the monthly payment before interest on the trailer: $120,000 / 240 months = $500/month
  Then subtract the cost of the trailer payment from the cost of the house payment to find the difference: $2000/month - $500/month = $1500/month
