For a particular product, Country A's supply and demand are represented by the following functions:
Qs = 2 + P; Qd = 52 - P
Suppose Country A is a small country (which cannot influence the world price). In free trade, Country C can export the product for $10 (PC = $10) and Country B for $15 (PB = $15).
Situation 1 - free trade: If there is free trade, where does Country A import (from Country B or Country C)? How much does it import?
