Answer:
5 bushels of corn
Step-by-step explanation:
The term opportunity cost refers to the loss from some potential gain when one alternative is chosen while leaving the other opportunities.
In United States, a worker in a day can produce 10 bushels of corn or can produce 2 shirts.
Thus the ratio is
10 bushels of corn : 2 shirts
or 5 bushels of corn : 1 shirts
Therefore the opportunity cost of a shirt in the United States is 5 bushels of corn.
Thus the answer is 5 bushels of corn.
