Answer:
6 pizza, 6 pasta
Explanation:
Now from the question we can see that Mia has comparative advantage in Pasta production and Mario in Pizza production.
Now before they both specialized, Mia's production was 6 pizza, 6 pasta. Mario also was making 6 pasta, 6 pizza.
So in total both were making 12 pizza and 12 pasta.
After they had specialized, Mario's pizza production is 18 pizza and Mia's pasta production is 18 pasta.
So we have that mia is producing 6 more pizza, 18-12 = 6
and Mario is also producing 6 more pasta.
So there is net gain of 6 pizza and 6 pasta.
