PS#3 Solutions Chapter 5 2. a. For business travelers, the price elasticity of demand when the price of tickets rises from  $200 to $250 is [(2,000 – 1,900)/1,950]/[(250 – 200)/225] = 0.05/0.22 = 0.23. For  vacationers, the price elasticity of demand when the price of tickets rises from $200 to  $250 is [(800 – 600)/700] / [(250 – 200)/225] = 0.29/0.22 = 1.32. b. The price elasticity of demand for vacationers is higher than the elasticity for business  travelers because vacationers can choose more easily a different mode of transportation  (like driving or taking the train). Business travelers are less likely to do so because time is  more important to them and their schedules are less adaptable. 3. a. The percentage change in price is equal to (2.20 – 1.00)/2.00 = 0.2 = 20%. If the price  elasticity of demand is 0.2, quantity demanded will fall by 4% in the short run  [0.20  ×  0.20]. If the price elasticity of demand is 0.7, quantity demanded will fall by 14%

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
