Two countries, A and B, currently produce two goods, wheat (W) and steel (S). They each have a linear production possibility frontier in both goods. For Country A, if it spends all of its available resources to produce wheat, it can produce 500 units of wheat and zero units of steel. If it uses all of its resources to produce steel it can produce 250 units of steel and zero units of wheat. For Country B, if it spends all of its available resources producing wheat, it can produce 400 units of wheat, and if it spends all of its resources on the production of steel, it can produce 400 units of steel. Look at the scenario Countries A and B. If country B produces 300 tons of steel, how many tons of wheat can it produce? A. 200.
B. 300.
C. 400.
D. 100.
