The accompanying table describes the hypothetical Canada B C D E PPC (product possibility curves) for furniture and Machinery 18 36 54 72 machinery in Canada and Mexico (both in millions of Furniture 45 36 9 tonnes per year). Before trade, Canada produces at 27 18 0 point C and Mexico at point D. After trade, 37 million Mexico A B C D E F tonnes of machinery is traded for 74 million tonnes of Machinery 0 8 16 24 32 40 fumiture. Furniture 200 160 120 80 40 a. The opportunity cost of machinery in Canada is tonne(s) of fumiture per tonne of machinery (Simplify your answer.) b. The opportunity cost of machinery in Mexico is tonne(s) of fumiture per tonne of machinery (Simplify your answer.) c. The opportunity cost of furniture in Canada is tonne(s) of machinery per tonne of furniture (Simplify your answer)
