Answer:
the gains resulting from trade:
Explanation:
Latalia's production     A.  B.  C.  D.  E.
pork                 4   3   2   1   0
beans                0   5  10  15  20
Trombonia's production  A.  B.  C.  D.  E.
pork                  8   6   4   2   0
beans                0   6  12   18  24
Latalia's opportunity cost of producing pork at C = 10 / 2 = 5 beans
Latalia's opportunity cost of producing beans at C = 2 / 10 = 0.2 pork
Trombonia's opportunity cost of producing pork at B = 6 / 6 = 1 bean
Trombonia's opportunity cost of producing beans at B = 6 / 6 = 1 pork
Latalia should specialize in the production of beans while Trombonia should specialize in the production of pork.
Total production will be 8 porks and 20 beans.
the gains resulting from trade:
