So, here's my problem:
Suppose that in Mexico it takes four labor hours to produce one shirt and 12 labor hours to produce one computer. Suppose that in the United States it takes four labor hours to produce one shirt and three labor hours to produce one computer. If both countries have 60 labor hours available, completely specialize according to comparative advantage, and trade 7.5 shirts for 7.5 computers, what is the value of the average wage in the United States after trade if the value of a shirt is $10 and the value of a computer is $100?
