A farmer has the ability to grow either corn or cotton or some combination of the two. Given no other information, it follows that the farmer's opportunity cost of a bushel of corn multiplied by his opportunity cost of a bushel of cotton. a. is equal to 0.

b. is between 0 and 1.

c. is equal to 1.

d. is greater than 1.

The correct answer is c. is equal to 1.

C) is equal to 1.

Explanation:

The opportunity cost of growing a bushel of corn instead of cotton = cotton bushels / corn bushels

The opportunity cost of growing a bushel of cotton instead of corn = corn bushels / cotton bushels

if we multiply both opportunity costs, the answer will always be 1 = (cotton bushels / corn bushels) x (corn bushels / cotton bushels).

i. e. a/b x b/a = 1 always
