If the value of a car is $22,000, and it depreciates by 15% each year. what is the car value after three years?

At the end of 1st year it depreciates by 15%, so it reduces by 100% - 15% = 85%

At the end of 2nd year it depreciates by 15% again, so it reduces by 100% - 15% = 85%

At the end of 3rd year it depreciates by 15% again, so it reduces by 100% - 15% = 85%

Net Value =  22000 * 0.85 * 0.85 * 0.85 = 13510.75

Value after three years = $13 510.75

You can use a calculater and divide the minutes by the $$, hope that you
