Suppose you were shown a demand curve for bananas and were asked to calculate price elasticity of demand. After doing so, you come up with 1.67 (absolute value). A classmate was asked to derive price elasticity of demand on the identical demand curve and got 0. 75 (absolute value). A bit perplexed, your classmate asks the professor which answer is right? The professor checks both calculations and says, "They're both right." Is this possible? If so, how and why?
