Current value of the boat = $45000
Rate at which the value decrease = 8.5%
Value decreased after 1 year =
![(8.5)/(100)*45000=3825](https://img.qammunity.org/2019/formulas/mathematics/high-school/tmdtiewjma4k71pnavt8x7iu2yggn7399s.png)
Hence, value becomes =
![45000-3825=41175](https://img.qammunity.org/2019/formulas/mathematics/high-school/e3kwjdyhyp8hw5vm8j8gqft0gknrvvs1d1.png)
Value decreased after 2nd year =
![(8.5)/(100)*41175=3499.875](https://img.qammunity.org/2019/formulas/mathematics/high-school/wbeul9b5yz4bsye7u27qiiott1o502ytz8.png)
Hence, value becomes =
![41175-3499.875=37675.125](https://img.qammunity.org/2019/formulas/mathematics/high-school/83vpbmldsgcmrwm3z4ix3q2qfr31gsowvp.png)
Value decreased after 3 year =
![(8.5)/(100)*37675.125=3202.385](https://img.qammunity.org/2019/formulas/mathematics/high-school/4wajmsa4rgih68snm12dcgm1cgk37y7qde.png)
Hence, value becomes =
![37675.125-3202.385=34472.74](https://img.qammunity.org/2019/formulas/mathematics/high-school/ri0lacksf5xz022vqebma9z8g2dkl3jfhy.png)
So, value of the boat after 3 years becomes $34472.74
