Answer:

The value of the car after 3 years is R$58.320.

O valor do carro ao final desse período é R$58.320.

Explanation:

The value of the car after t years is given by the following equation:


V(t) = V(0)(1-r)^(t)

In which V(0) is the initial value and r is the yearly depreciation rate.

In this question, we have that:


V(0) = 80000, r = 0.1

So


V(t) = V(0)(1-r)^(t)


V(t) = 80000(1-0.1)^(t)


V(t) = 80000(0.9)^(t)

Value of the car at the end of 3 years:


V(3) = 80000(0.9)^(3) = 58320

The value of the car after 3 years is R$58.320.

O valor do carro ao final desse período é R$58.320.
