Both a college student and a well$-$known attorney want to attend the Dodger game on Friday night. The college student waits in line for hours to purchase a ticket to the game and pays a relatively low money price. The attorney does not wait in line. Rather than spend hours in line, the attorney purchases his ticket through a ticket broker, paying a much higher money price than the college student. Using the economic concept of opportunity cost, explain why the attorney and the student use different ways to buy their tickets.
