Suppose that, in a Classical model with two goods, Germany can produce 50 units of steel with one day of labor and 30 units of textiles with one day of labor; Switzerland can produce 45 units of steel with one day of labor and 45 units of textiles with one day of labor.

Answer: must be less than 10 euros per day.
