Colin buys a car for £28100. It depreciates at a rate of 4% per year.
How much will it be worth in 6 years?
Give your answer to the nearest penny where appropriate.

The amount the car will be worth after 6 years is £21,917 and 22 pence

Step-by-step explanation:

The amount for which Colin buys the car, PV = £28,100

The amount by which the car depreciates each year, r = 4%

The number of years after which the value of the car is sought, n = 6 years

The future value, FV, based on an annual depreciation is given as follows;

Substituting the known values gives;

Therefore, the amount the car will be worth after 6 years, future value FV₆ = £21,917 and 22 pence

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
