Answer:
Kyoko
Explanation:
Based on the information provided it can be said that in this scenario the individual with the lowest opportunity cost of completing the task is Kyoko. This is because opportunity cost refers to what is being lost when choosing one opportunity or decision as opposed to another, and in this scenario since Kyoko is way faster at changing the brakes than Jacques then he will be losing less money by changing the brakes than Kyoko.
Kyoko: 160/2 = $80 opportunity cost for changing the brakes.
Jacques: 20*5 = $100 opportunity cost for changing the brakes.
