The demand for hamburgers is estimated from this theoretical model:
Q = kPaIbAce, where Q = units per day, P = price per unit, A = advertising budget per month by sellers, I = per capita income of consumers, and e = a random error. In a recent study, one researcher estimated the log-linear form of this equation with regression analysis as: log Q = 2.5 - 0.33 log P + 0.15 log I + 0.2 log A. Explain what the coefficients of log P, log I, and log A reveal about this product.
