Sustainable Yield and Net Benefits vs. Effort Levels

Create a combined line and scatter plot. The x-axis represents effort levels (E), while the y-axis displays sustainable yield (h(E)) and net benefits (Net Benefits(E)). Plot h(E) and Net Benefits(E) as lines, highlighting the effort levels (E = 45, E = 40, E = 60) with distinct markers. Overlay a horizontal line for the tax at t = 10, using a contrasting color for clarity. This succinctly presents the key relationships for the academic audience.
