Solution

First, we need to find the rate at which the car's value is decreasing. We know that the value of the car decreases from 15,000to15,000 to 11,000 in 2 years (from year 3 to year 5). So, the rate of decrease per year is:

(15,00015,000 - 11,000) / 2 = $2,000 per year

This means the value of the car decreases by $2,000 each year.

Next, we need to find the initial value of the car. We know that after 3 years, the car's value is $15,000. So, the initial value of the car is:

15,000+315,000 + 3 * 2,000 = $21,000

Now, we can write the linear equation that represents the value of the car over time. Let's denote the value of the car as V and the number of years as t. The equation is:

V = 21,00021,000 - 2,000 * t

Finally, we can use this equation to find the value of the car after 8 years:

V = 21,00021,000 - 2,000 * 8 = $5,000

So, the value of the car after 8 years is $5,000.
