Answer:
Opportunity Cost:
Opportunity cost can be denied as the benefit a person has received but giving up taking another course of action. In other words, it can be defined as the next best alternative.
Given that the Nike women's store earns a profit in excess of $437,000. The owner of the store pays $18,000 per month as rent. A real estate agent approached the owner and informed her that she could add $7,700 per month to her firm's profits by renting out the portion of her store that she uses as a fitness studio.
From the given question the opportunity cost of continuing to operate the fitness studio within the store is $7,700.
