Multiple Choice

Suppose the domestic supply (Q^S_U.S.) and demand (Q^D_U.S) for bicycles in the United States are given by the following set of equations: $$\begin{array} { l } Q ^ { \mathrm { S } } \mathrm { U.S } . = 2 \mathrm { P } \\\mathrm { Q } _ { ^\mathrm { D } U . S } = 200 - 2 \mathrm { P } .\end{array}$$ Demand (Q^D) and supply (Q^S) in the Rest of the World are given by the equations: $$\begin{array} { l } Q ^ { S } = P \\Q ^ { D } = 160 - P .\end{array}$$ Quantities are measured in thousands and price in U.S. dollars. After the opening of free trade with the Rest of the World, if the world price of the bicycles settles at $60, the U.S. will:

A) export 40,000 bicycles.
B) export 60,000 bicycles.
