The population, $P$, of a particular species of insect in a controlled environment can be modelled by the function
$$P(t) = A e^{kt}$$,
where $t$ is the time in days, and $A$ and $k$ are positive constants. Initially, at $t = 0$, the population is 100.
After 7 days, the population has grown to 350.
c. Explain what the inverse function $t(P)$ represents in the context of the problem.
