    Not 1000 every 4 hours. Just 1000 over the first 4 hours. In the formula, P is the amount at any time, A is the initial amount, k is a constant we have to find, and t is the time.

    Start with P = 5000e^(kt)

    Plug in the given values for P and t and solve for k.

    @boogaboo this is not a linear function where the rate is constant

    when P = 5000 t =0 when P = 6000 t = 4 find P when t = 17

    grows by a factor of \(\frac{6000}{5000}=\frac{6}{5}\) every 4 hours model as \[\huge P(t)=5000\times( \frac{6}{5})^{\frac{t}{4}}\]

    if you want to know the population in 17 hours replace \(t\) by \(17\) and compute \[\huge P(17)=5000\times( \frac{6}{5})^{\frac{17}{4}}\]
