(1) Calculate the price elasticity of demand for the following demand functions:
(a) Q = 5 - ln(P) for P=8
(b) Q = 2000 - 0.5P3 for P=15
(c) Q = (12-P)^2 for P=10
(d) P= 2/Q for P=1


(2) Advertising:
Assume a firm's advertising elasticity is known to be 0.8.
The firm's demand function is given by Q=100 - 2P. The firm charges a price of
P=$3.50 for its product. Calculate the profit maximizing level of advertising per sale.
