Answer:
d. 100 units of wheat and 100 units of fish.
Step-by-step explanation:
In the actual case, we have 10 weorkers in each country, 5 of them producing the product in which they have a competitive advantage and five of them in the other product, so, we have
Boatland => 5 workers producing wheat=5*5= 25 wheat/ year
5 workers producing fish= 5*25= 125 fish / year
Farmland => 5 workers producing wheat=5*25= 125 wheat/ year
5 workers producing fish= 5*5= 25 fish / year
Combined output:
- Wheat= 25+125 = 150
- Fish: 125+25 = 150
If they specialize in the one product that each one has competitive advantage on:
- Boatland's Annual output= 10 workers producing 25 fish/ year = 250 fishes/ year.
- Farmland's Annual output= 10 workers producing 25 wheat/ year = 250 wheat/ year.
The combined output is 250 of each product which is 100 units more that the original output for each one of them.
