Answer: In 5 years it will be worth £455
Step-by-step explanation:
Step 1 
 Given 
The cost of the T.V. for Colin = £530.
The rate of depreciation per year = 3%
Time/ period = 5 years
Formulae to be used 
F = P  X (1 - r) ^ n
where
F = the future value after depreciation
P = the present value.
r =the interest rate per time period 
n = the time/ periods
 Step 2--- SOLVING
F = P  X (1- r) ^ n
F= 530 x (1-0.03) ^ 5
=530 x 0.858734
=£455.129
 Rounding up to the nearest penny where appropriate = £455
