solution:
(A) = P( 1 + r/n) ^nt
P(Principal) = £200 000
r(interest rate) = 1.6% = 0.016
The total amount been saved after 4 years is calculated as:
A = P( 1 + r/n) ^ nt
A = £200,000( 1 + 0.016/1)¹× ⁴
A = £200,000(1.016)⁴
A = £213,110.48991
A = £ 213,110.49
Claire will get approximately £ 213,110.49 within 4 years.
