Question 3. You have developed a new energy drink, Green Hornet. You have not been sure about the optimal price to charge. You also are trying to gure out the cross-price elasticity of the quantity of Green Hornet with respect to the price of a new energy bar called Arise. You are not certain whether consumers consider the two services to be substitutes or complements. In the first year of operation you experimented by randomly adding and subtracting different amounts from a base price in 80 test markets around the country. You then had a consulting rm run a regression of the quantity of Green Hornet (Q) in each market as a function of the price of Green Hornet (P), the price of Arise (A), and the per capita incomes in thousands of dollars (Y) of the people in the different markets. The regression results led to the following equation All coefcients are statistically signicantly different 'om zero. Q= 35 - 5P+5A+2Y. The means from the sample were 100 for quantity (Q), 10 for the price of Green Hornet (P), 15 for the price of Arise (A), and 20 for per capita income in thousands (Y). In making your elasticity calculations just use the numbers as they are. For example, do NOT convert the mean of per capita income in thousands from 20 to 20000. a. Based on the information in the regression equation, what is the price elasticity of demand for Green Hornet? Is it elastic, unit elastic, or inelastic? What does it say about the number of substitutes? Explain your answer. [8 points}
