Suppose that the MASU managed to get Beyonc to play a concert at Convocation Hall. Ticket price is $500 per ticket. At the same time, Gheorghe Zamfir (The Master of the Pan Flute) is playing in Brunton Auditorium. Ticket price is $100 per ticket. You've always wanted to see Zamfir, and consistently told your friends that you would pay up to $200 to see him in concert. What is your opportunity cost of going to the Beyonc concert? Please provide your answer in monetary terms and show your reasoning.
