Answer:
highest paying position
Step-by-step explanation:
In the field of economic, "opportunity cost" may be defined as the loss of the potential gain from among the alternatives that were provided when one of the alternatives were chosen over the other alternatives. In other words, it is the loss of a benefit for a person who could have enjoyed if that person would have not taken the choice.
Opportunity cost helps to make decisions properly.
In the context, Ishmael has been offered four potential jobs from highest salary to lowest salary. Based on this information, the opportunity cost of Ishmael to accept the position which pays him $56,000 is the highest paying job.
