Answer:
A. 1/3 computers
B. 0.6 computers
Explanation:
A. The opportunity cost incurred by the US to make cars is the number of computers it would have to give up to make a car.
The US can either make 12 cars or 4 computers. For every car made therefore the US forgoes;
= 4/12
= 1/3 computers.
B. The same logic applies to Japan. They can either make 10 cars or 6 computers.
Their opportunity cost for cars is therefore;
= 6/10
= 0.6 computers
