When the price of soda was $7.35 per case, people bought 274? cases of soda and 3346 cases of water. a. Calculate the cross-price elasticity of demand for soda and water. Write down your initial equation and then show the steps to get your final answer. b. Use your answer to a to explain how soda and water related? c.
