Answer:
Jane's total cost is $60,000.
Step-by-step explanation:
This is because of the phenomenon called Opportunity Cost.
Simply put, opportunity cost is the cost of the next best alternative use of resources when a choice is made at the detriment of another.
We can also define it by saying, Opportunity Cost is the forgone alternative.
So we know she spent $50,000 to start her business, but would have made 10% of $100,000 which is $10,000 which is the opportunity cost, she has incurred a total cost of $60,000.
