3. This question just asks for total output if the two countries specialize in producing the product where each has a comparative advantage.

We've already established that Country 1 has a comparative advantage in burrito production, so it should specialize and produce 150 burritos and 0 computers.

We know that Country 2 has a comparative advantage in computer production, so it should specialize and produce 100 computers and 0 burritos.

Any total outputs higher than choice c. "150 burritos and 100 computers." aren't feasible, and lower than that come from not specializing.

Country 1		Country 2
Burr.	Comp.	Burr.	Comp.
150	0	100	0
120	10	80	20
90	20	60	40
60	30	40	60
30	40	20	80
0	50	0	100
