conversations.value: This math problem has got me stumped: Gary bought a boat for $9000.  Over the first year it depreciated 30%.  The second year it depreciated another 30%.  The third year it depreciated 20%.  How much is the boat worth after the three years?
  Can you show me the way?
conversations.from: assistant
conversations.value: After first year:9000(.30)=2700
  9000-2700=6300
  After second year:6300(.30)=1890
  6300-1890=4410
  After third year:4410(.20)=882
  4410-882=3528$
