单选题 Alice Costain operates a convenience store in the financial district of London. ff Costain increases the price of a Magnim ice cream bar from 1.00 to 1.15, weekly sales decrease from 200 units to 180 units. Which of the following statements is most accurate? A. The price elasticity of demand is -0.66. B. The slope of the demand curve equals the elasticity of demand. C. The price increase will lead to an increase in total value of Magnim ice cream bars.

【正确答案】 C

【答案解析】The absolute value of price elasticity determines whether demand is elastic or inelastic. Here, the absolute value is less than 1, and demand is inelastic. When demand is inelastic, a price increase will lead to an increase in total expenditure on the good. The slope of the demand curve is not the same as the elasticity of demand. Elasticity is measured from a specific point.
