Question 1169074
<font color=black size=3>
Opportunity cost is the value of what you give up when you make a decision. In this case, Janice's opportunity cost is the amount of money she would have earned if she worked instead of going to the basketball game.


She normally works 5 hours and makes $7 an hour, so she would have made 5*7 = 35 dollars
Adding on the tips means she would have made 35+35 = 70 dollars.


Answer: Opportunity cost = 70 dollars


Note: the other values don't factor into the opportunity cost since we only focus on what Janice would give up when she makes a certain decision.
