Q = 960 - 1.2P + 1.4Y + .003Awhere, Q and P are the quantity and price of the product respectively, Y is income, and A is the advertising expenditures. All the variables are in the natural logarithmic form and all the estimated coefficients are statistically significant. The average annual sale and the average price of the product are 60000 units and $8000 respectively.A. Price elasticity of demand is -------------, income elasticity of demand is ---------, advertising elasticity of demand is -----------------.
