Answer:
It should be greater than $36
Step-by-step explanation:
The opportunity cost of working is the amount of money sacrificed or could have earned if the individual was not working. In this case, Claire has decided to go with her friend which means that the opportunity cost of not working is less than the benefits receives from going out. Because she is not working it means that the opportunity cost of working is more than 36 dollars, which is the income she could have earned in 3 hours.
