Answer:
a) see attached image
b) Atlantis's opportunity cost of producing one helmet = 200 / 100 = 2 baseballs
c and d) Atlantis's opportunity cost of producing one baseball = 100 / 200 = 0.5 helmets
Zanadu's opportunity cost of producing one baseball = 100 / 400 = 0.25 helmets ⇒ Zanadu has a comparative and absolute advantage in the production of baseballs
e) yes, Atlantis would produce 100 helmets, and if it trades 50 to Zanadu, it will get 150 baseballs in return. So it will gain from trade. If Zanadu produces 400 baseballs and trades 150 of them for 50 helmets, it will also benefit.
