Suppose that business travelers and vacationers have the following demand for airline tickets from Los Angeles to San Francisco:
Price
$150
$200
$250
$300
Quantity Demanded
(business travelers)
35,000
30,000
26,000
20,000
Quantity Demanded
(vacationers)
25,000
21,000
14,500
11,000
1. As the price of tickets rises from $200 to $250, what is the price elasticity for both
(a) business travelers and (b) vacationers ?
2. Why might vacationers have a different elasticity than business travelers?
3. What would be the Exact Quantity Demanded and change in Total Revenue if the
Airlines Change the Price for Business Travelers from $200 to $230?
