Note this question has 2 parts! You are an economist for the City Subway Commission. Presently, the price of a subway ride is 80c, and 200,000 seats are filled weekly. The price elasticity of demand for subway rides is -0.40, and the income elasticity of demand is -0.60. A. The Commission wants to ensure that the subway has enough excess capacity to handle any extra demand that might occur during an economic decline. If a recession lowered area incomes by 5%, how many additional seats per week would the subway need? Solve this question numerically and explain. B. The Commission has just approved a subway price increase of 10c per ride. The Commission wants to know if it can use the opportunity to retire two aging subway cars that each provide 8,000 seats weekly. When the price hike goes into effect, can neither, one, or both cars be retired? Solve this question numerically and explain. Type your answers (including calculations) in the box directly
