Answer:
5)
![y=42000(1-0.08)^6](https://img.qammunity.org/2020/formulas/mathematics/middle-school/yd7elmcen955n7dty60ae7lkxupaqqwped.png)
6) 25467
Explanation:
5) Use the formula;
![y=y_0(1-r\%)^t](https://img.qammunity.org/2020/formulas/mathematics/middle-school/a4r030vbrnjvcsjaibzp52t2d0ac8rz741.png)
where
dollars is the initial value of the car.
![r\%=0.08](https://img.qammunity.org/2020/formulas/mathematics/middle-school/5eogv92kuoo3g4b5kp1wmf0fleg058w9g7.png)
and
t=6 years.
We plug in these values to obtain;
![y=42000(1-0.08)^6](https://img.qammunity.org/2020/formulas/mathematics/middle-school/yd7elmcen955n7dty60ae7lkxupaqqwped.png)
Third choice is correct
6) The expected value of the car after 6 years is
![y=254666.910](https://img.qammunity.org/2020/formulas/mathematics/middle-school/khygl63fds2ugfs5i73hnihz43g06l2s3s.png)
We round to the nearest tenth to obtain;$ 25467
