Textbook Problem

In an hour, David can wash 2 cars or mow 1 lawn, and Ron can wash 3 cars or mow 1 lawn. Who has the absolute advantage in car washing, and who has the absolute advantage in lawn mowing?

  1. a. David in washing, Ron in mowing.
  2. b. Ron in washing, David in mowing.
  3. c. David in washing, neither in mowing.
  4. d. Ron in washing, neither in mowing.

To determine
The absolute advantage.

Answer

Option ‘d’ is the correct answer.

Explanation

Option (d)

Ron has the absolute advantage in washing, since he can wash 3 cars per hour, while David can only wash 2 cars per hour. None has the absolute advantage in mowing as both can only mow 1 lawn in an hour’s time. So option ‘d’ is correct.

Option (a)

David can only wash 2 cars per hours, whereas Ron can wash 3 cars in the same amount of time. So David does not have the absolute advantage in washing cars. Also, both do not have the advantage over the other in mowing the lawn. So option ‘a’ is incorrect.

Option (b)

Ron has an absolute advantage in washing, since he can wash 3 cars per hour, while David can only wash 2 cars per hour but both do not have the advantage over the other in mowing the lawn. So option ‘b’ is incorrect.

Option (c)

None has the absolute advantage in mowing as both can only mow 1 lawn in an hour’s time but Ron has the absolute advantage in washing, since he can wash 3 cars per hour, while David can only wash 2 cars per hour.  So option ‘c’ is incorrect.
