Using the midpoint method, calculate the price elasticities of demand for group A and group B. b. Explain how the discount will affect total revenue from each group. c. Suppose Amazon.com knows which group each customer belongs to when he logs on and can choose whether or not to offer the 10% discount. If Amazoncom wants to increase its total revenue, should discounts be offered to group A or to group B, to neither group, or to both groups? Answer questions a, b, and c above (summarized below) A. Calculate the midpoint Price Elasticity of Demand for groups A and B. B. Explain how the discount will affect Total Revenue of each group. C.
