The rate constant $r$ if the population doubles in $30$ days. Where a population $p$ of field mice that grows at a rate proportional to the current population that is, $dp/dt=rp$.

Population Problems. Consider a population $p$ of field mice that grows at a rate proportional to the current population, so that $dp/dt=rp$.

Find the rate constant $r$ if the population doubles in $30$ days.

Find $r$ if the population doubles in $N$ days.
