Explanation:
From these numbers, we can conclude that USA has a comparative in producing cars and France has a comparative advantage in producing bottles.
Opportunity cost shows that how many units of one good have to be foregone in order to produce one additional unit of other good.
In USA:
Opportunity cost of producing bottles = 
= 0.75
Opportunity cost of producing cars = 
= 1.33
In France:
Opportunity cost of producing bottles = 
= 0.55
Opportunity cost of producing cars = 
= 1.8
Above calculations clearly shows that USA has a lower opportunity in producing 1 unit of car as compared to the France, so it has a comparative advantage in producing cars.
Whereas, France has a lower opportunity in producing 1 unit of bottle as compared to the USA, so it has a comparative advantage in producing Bottles.
