Answer:
The US has absolute advantage in making cars. An additional worker makes 5 times higher cars than a Mexican worker.
Step-by-step explanation:
The US has the absolute advantage than Mexico in making both products since its Marginal Product of Labor (MPL) (i.e. the number cars that an additional worker produces) is higher. The US also enjoys absolute advantage because it incurs less cost in making car (or even airplane) than does Mexico in making either car (or even airplane). One can then conclude that the US has the absolute advantage in the making of cars.
