A car depreciates at a rate of 30% per year. How much will a $20000 car be worth after 5 years?
The car depreciates by 30% every year. So if its initial value is V, the next year it will be V*(1 - 30%) = V*(1 - 0.3) = V*0.7.
The year after that it will be V*(0.7)^2 and the value similarly decreases so that after n years it is equal to V*(0.7)^n.
Now, it is given that the initial value is $20,000. Therefore after 5 years it will be 20,000*(0.7)^5 = $3361.4
The required value of the car is $3361.4
