The value of a new car is £18,000. The value of the car decreases by 25% in the first year and 12% in each of the next 4 years. Work out the value of the car after 5 years?

The initial value of the car is 18000. To subtract 25% of 18000 one must times 18000 by 0.75 which equals 13500. Next, one must times 13500 by 0.88 to the power of 4 which equals 8095.89 to 2 decimal places which is the final answer.
