需求价格弹性
弹性衡量数量对价格变动反应的百分比强度；其数值大小——从完全无弹性到完全有弹性——按价格变动对购买者的影响程度对市场进行分类。

5. Classifying the response
A metro authority raises fares by 8 percent and ridership falls by 2 percent over the following year. What is the price elasticity of demand, and how is this demand best described?
6. Which demand is more elastic
Rank these three demands from most to least price elastic, the demand for Coca-Cola, the demand for cola soft drinks in general, and the demand for all beverages.
7. Compute the elasticity
A rose grower raises the price of a bouquet from 20 to 24 dollars, and weekly sales fall from 100 bouquets to 80. Using the simple percentage method with the original values as the base, compute the price elasticity of demand as a positive number and write the number.
8. Classifying the fare response
A metro authority raises fares by 10 percent and ridership falls by 5 percent. What is the price elasticity of demand, and how is it classified?
9. Which demand bends most
Which of these demands is most likely to be the most price elastic?
10. The elasticity ratio
A price rise of 10 percent cuts quantity demanded by 30 percent. Compute the price elasticity of demand as an absolute value, and write the number.
