conversations.value: I need a clearer understanding of how to solve: James buys a plane.  The plane cost $150,000.  He pays $5000 a month to rent a hanger to keep it in.  He also spends twice as much as that on fuel per month.  How much did it cost him to get and maintain the plane for the first year?

conversations.value: The fuel cost 5000*2=$10000 per month
  With the hanger that means he pays 10000+5000=$15,000 per month
  So he spends 12*15000=$180,000 a year
  That means the total cost was 150,000+180,000=$330,000
