Q1) A firm has estimated following demand function for its product:
Q = 58 - 2 P + 0.10 I + 15 A
where Q is quantity demanded per month in thousands, P is product price, I is index of consumer income, and A is advertising expenditures per month in thousands. Suppose that P = $10, I = 120, and A = 10. Use point formulas to complete elasticity computations indicated below.
(i) Compute quantity demanded.
(ii) Compute advertising elasticity of demand and describe its meaning.
