1. The problem statement, all variables and given/known data City "A" wants to measure benefits of a stadium it built. Currently admission is free and 10 000 people per month visit the stadium. In a comparable city, a similar stadium charges $5 for admission and receives 2000 visitors per month. Assume a linear demand curve goes through these two points. Estimate the gross benefit of the stadium in city "A". 2. Relevant equations N/A 3. The attempt at a solution Method: 1) Linear line is drawn with both points, i.e. (0, 10 000) and (5, 2000) on it; 2) Draw a horizontal line from the linear line to the y-axis; 3) Find the area. But I am not sure if this is the right method. Does anyone have any idea what method could be used? There was nothing else said in the question.
