Step 1

1 of 4**a)**
Let $k_1$ be the constant of proportionality for the birth rate, $k_2$ the constant of proportionality for the death rate, and $y(t)$ the population at time $t$.

According to the given data, we obtain the ODE

$y' (t)= k_1y(t) - k_2y(t).$

This is the mathematical model of the biological process.

Let's solve the ODE.
