Question 894472
The problem is asking for the interest accrued, we use the following formula

FV = PV × (1+r)^n

where FV = Future Value
PV = Present Value
r = annual interest rate
n = number of periods

FV = 88500 x (1+0.05)^4

FV = 107572.30

therefore interest accrued is = 107572.30 - 88500 = 19072.30 pounds
