1. **Problem Statement:** We want to find the ratio of the initial populations of rats ($R_0$) and skunks ($S_0$) that allows both species to survive in the long term. 2. **Backgro

1. The problem asks for the ratio of $R_0$ to $S_0$ for $X_0$ in a stable population. 2. In population dynamics, $R_0$ often represents the net reproductive rate, $S_0$ the initial
