    The nearest penny will be £9146.6

    Step-by-step explanation:

    A = P[1 + (r/n) ]^ (nt)

    A = final amount

    P = initial principal balance

    r = interest rate

    n = number of times interest applied per time period

    t = number of time periods elapsed

    A = 8300 [ 1 + {1.4 / (7*100) }]^ (7*7)

    A = 8300 [ 1 + {0.002}]^ (49)

    A = 8300 [ 1.002 ]^ (49)

    A = 8300 [ 1.102 ]

    A = £9146.6
