Problem
Christopher bought a $125 ticket to attend Nickelback concert in Red Rocks. Because it is his favorite rock group, he would be willing to pay up to $200 to attend the concert. However, his friend Keith invites Christopher to go with him to Water World in Denver, but he is only willing to pay up to $100. What is his opportunity cost of going to the Nickelback concert in Red Rocks?
