    Answer: 7.2 months

    Step-by-step explanation:

    Hi, to answer this question we have to substitute f (x) = 500 in the equation given:

    f (x) = 100 (1.25) ^x

    500 = 100 (1.25) ^x

    Solving for x (number of months)

    500/100 = 1.25^x

    5 = 1.25^x

    log 5 = log 1.25^x

    log 5 = x (log 1.25)

    log 5 / log 1.25 = x

    x = 7.2 months
