# Absolute and Comparative Advantage Help

I started studying microeconomics and I am having trouble figuring our how can I find the "?" values in this table? If someone could help me I would be really grateful.

╔════════════════════════════════╦════════════════════════════════╗
║                            Country A                            ║
╠════════════════════════════════╬════════════════════════════════╣
║            Bananas             ║            Oranges             ║
╠════════════════════════════════╬════════════════════════════════╣
║ Wage = 12                      ║ Wage = ?                       ║
║ Marginal Product of Labour = 2 ║ Marginal Product of Labour = ? ║
║ Price = ?                      ║ Price = 4                      ║
╚════════════════════════════════╩════════════════════════════════╝


In regard to the bananas I believe the Price must be equal to the Wage = Marginal Product of Labour multiplied by the Price or in other words 12 = 2 * X => X = 6 => P = 6

However, I am not sure in the case of oranges where I have two unknown variables how to get the wage and the marginal product of labor in Oranges.

PS: Thank you in advance. In order to simplify the problem I skipped country B, because trade is not allowed between the two countries in this exercise.
