Answer:
Actual value after 5 years is £1344 more than John's value.
Step-by-step explanation:
Johns estimate:-
V = k/t (inverse proportionality) where V = value of the car and t = it's age.
When t = 2, V = £12,000:-
12,000 = k/2 giving k = 24,000
Therefore the value at 5 years of age, according to John's proposition is
V = 24,000 / 5 = £4,800
The actual value using the given depreciation is
12000(1 - 0.2)^3 = £6144
Difference is £1344
