Answer:
Gilberto
Explanation:
Juanita can dig the necessary holes for the fence in one hour. At work, she makes $200 per hour. This means that the opportunity cost of her digging the holes would be $200. On the other hand, Gilberto earns $15 per hour as a cobbler. Moreover, it takes him 5 hours to dig the holed. Therefore, the opportunity cost of him digging the holes would be $75 (15*5). This means that Gilberto has the lower opportunity cost of completing the task.
