How much value did the boat lose in the first year? ** After first year:9000(.30)=2700
How much is the boat worth after the first year? ** 9000-2700=<<9000-2700=6300>>6300
How much value did the boat lose in the second year? ** After second year:6300(.30)=1890
How much is the boat worth after the second year? ** 6300-1890=<<6300-1890=4410>>4410
How much value did the boat lose in the third year? ** After third year:4410(.20)=882
How much is the boat worth after the third year? ** 4410-882=<<4410-882=3528>>3528$
