brian invests £4700 into his bank account he recieves 5.5% compound intrest how much will brian have after 3 years?

Brian will have £817.8

Step-by-step explanation:

Principal = £4700

interest = 5.5% = 0.055

n = 3 years

Amount = [ (Principal * (1 + interest) ⁿ) - Principal]

Amount = [ (4,700 * (1 + 0.055) ³) - 4,700]

Amount = [ (4,700 * (1.055) ³) - 4,700]

Amount = [ (4,700 * 1.174) - 4,700]

Amount = [5,517.8 - 4,700]

Amount = £817.8
