-The opportunity cost refers to the benefit that you don't receive when you choose an option over another one.
Step-by-step explanation:
The opportunity cost of going to Florida would include the amount you won't spend on the trip that is $700. Also, it includes the benefit of staying at home that is working for $80/day for 5 days that is equal to $400 minus the expenses that are $100. According to this, the opportunity cost is: $700+$300= 1,000.
