Given:

Initial value of car = 20,000

Depreciation or decreasing rate = 10% = 0.10

To find:

The equation that gives the value of the car.

Solution:

It is given that the value then depreciates or decreases by 10% of in initial value each year. It means the depreciation value is same for each year, i.e., 10% of initial value.


10%\text{ of }20000=(10)/(100)* 20000


10%\text{ of }20000=2000

So, the value of car decreased by 2000 per year.

Let y be the value of can after x years.

Then, the value decreased in x years is 2000x.

So, the values of the car is


y=20000-2000x

Therefore, the required equation is
y=20000-2000x.
