    Somebody please help me with this stupid simple log type question

    If I have this, how do I find t:

    1850 = 2800(0.12)e^0.2t divided by 1+0.12e^0.2t

    PLEAASSSSSSSSSSSSEEEEEE or I'll resort to violence.

    Start by multiplying both sides by 1+0.12e^0.2t

    Right, I did this and got:

    2072e^0.2t = 336e^0.2t

    What now :confused:

    1850 = \frac {2800(0.12e^{0.2t})}{1 + 0.12e^{0.2t}}

    1850 + 222e^{0.2t} = 336e^{0.2t}

    114e^{0.2t} = 1850

    e^{0.2t} = \frac {1850}{114}

    0.2t = ln(\frac {1850}{114})

    t = 5ln(\frac {1850}{114})

    simples
    ****, i didn't even think that you can't just add 1 and 0.12
    thank you pheylannn rep!
