A car depreciates in value by 10% each year. If a car was bought for £4500, how much will the value of the car decrease by after 3 years?

 £1,219.5

Step-by-step explanation

Original price of car = £4500,

If the car depreciates by 10% after first year

New price = 90% of 4500

New price = 0.9 * 4500

New price = £4050

Second year

Price = 90% of 4050

Price = 0.9 * 4050

Price = £3,645

Third year:

Price = 90% * £3,645

Price = 0.9 * £3,645

Price = £3,280.5

Decrease in value = £4500 -  £3,280.5 = 1,219.5

Hence the  value of the car would have decrease by  £1,219.5 after 3 years

7 - 9 = -2

reversed:

-2 + 9 = 7
