For a small country called Boxland, the equation of the domestic demand curve for cardboard is QP = 380 2P, where Q' represents the domestic quantity of cardboard demanded, in fons, and P represents the price of a ton of cardboard. For Boxland, the equation of the domestic supply curve for cardboard is 08 = -60 + 3P, where Q represents the domestic quantity of cardboard supplied, in tons, and P again represents the price of a ton of cardboard. Refer to Scenario 9-1. Suppose the world price of cardboard is $139. Then Boxland's gains from international trade in cardboard amount to O $28,356.00. O $6,502.50 O $3,251.25. O $13,005.00
