A: -1
B: -25
C: -0.2
D: -10

D: -10
举一反三
- For a horizontal demand curve, A: the slope is undefined, and the price elasticity of demand is equal to 0. B: the slope is equal to 0, and the price elasticity of demand is undefined. C: both the slope and price elasticity of demand are undefined. D: both the slope and price elasticity of demand are equal to 0.
- When demand is inelastic the price elasticity of demand is
- Price elasticity of demand along a linear, downward-sloping demand curve increases as price falls. A: 正确 B: 错误
- 中国大学MOOC: Price elasticity of demand along a linear, downward-sloping demand curve increases as price falls.
- If the price elasticity of demand for a good is 1; then doubling the price of that good will leave total expenditures on that good unchanged
