Answer:
The potential 6 burgers in this situation are the opportunity cost.
Step-by-step explanation:
The opportunity cost is the cost of the alternative not taken when faced with two options. In this case, the business could have either used the 4 resources to make 8 fries or 6 burgers, and since it opted for the fries, the opportunity cost is the 6 burgers, including the revenue that the restaurant could have obtained from the sale of those burgers.
