11. Suppose there are only two planets in the universe, Zenope and Zuranda. On each planet, its inhabitants
consume two products—coffee and fried chicken. Each planet has an equal population. Producing solely
coffee, Zenope can produce 50 units of coffee, while Zuranda can produce 80 units of coffee. Producing
solely fried chicken, Zenope can produce 25 units, while Zuranda can produce 30 units.
