Answer:
The answer is 27 hours
Step-by-step explanation:
Solution
The Comparative advantage depends on production of the lower opportunity cost
The opportunity cost of a production is =maximum production of other good /maximum production of the good
Now,
The opportunity cost of hot dog bun for town A =10/4=2.5
Thus,
The opportunity cost of hot dog bun for town B=6/10=0.6
So,
The town B has a comparative advantage in hot dog buns and A in sausages
Town A will produce-only sausages and it will take the time of
time in hours =total required a quantity of the good /number of products in an hour
Now,
The time for Town A for sausages=120/10=12 hours
The time for Town B for hot dog buns=120/8=15 hours
Therefore, The total time =12+15=27 hours.
