We have the relative cost for Orion of producing one Ton of Granite is: 9/6 = 1.5 Bushels of Blueberries, while the relative cost for Scorpius of producing one ton of Granite is : 7/3 = 2.33 Bushels of Blueberries. Thus, Orion has comparative advantage of producing Granite.
We have the relative cost for Orion of producing one Bushels of Blueberries is: 6/9 = 0.67 ton of granite, while the relative cost for Scorpius of producing one Bushels of Blueberries is : 3/7 = 0.43 ton of granite. Thus, Scorpius has comparative advantage of producing Blueberries.
