Answer:
Mike has a comparative advantage in the production of computers.
Explanation:
Mike's opportunity cost of producing trucks instead of computers = 10 / 10 = 1.
Mike's opportunity cost of producing computers instead of trucks is 10 / 10 = 1.
Debra's opportunity cost of producing trucks instead of computers = 3 / 9 = 0.333.
Debra's opportunity cost of producing computers instead of trucks = 9 / 3 = 3.
Mike's opportunity cost of producing computers instead of trucks is 1, while Debra's is 3. Therefore, Mike has a comparative advantage in the production of computers.
