(5,234) (1.29) (175) (0.12) (0.17) (0.13)

R-squared = 0.68 SEE = 786 F = 21.25

where

Q = quantity;

P = price of basic model (=7,000);

A = advertising expenditures, in thousands (=52);

PPC = average price of a personal computer (=4,000);

Pc = average price of a leading competitor’s workstation (=8,000);

a) Compute the elasticities for each of the variables. Discuss the relative impact thateach variable has on demand.
