Suppose the demand for X is given by Qxd = 100 + 2PX + 4PY + 10M + 2A, where PX represents the price of good X, PY is the price of good Y, M is income, and A is the amount of advertising on good X. Good X is:
a. an inferior good.
b. a normal good.
c. a Giffen good.
d. a complement.

The generalized demand and supply functions for good X are
Qd = 10 -2Px - 4PY + M Qs = 10 + 2PX
|
Where: QD = quantity demanded of good X PX = price of good X M = consumer income PY = price of good Y |
QS = quantity supplied of good X PX = price of good X

A. Are good X and good Y substitutes or complements? Why?
B. Is good X a normal good or an inferior good? Why?
C. What is the demand function when PY = $4 and M = $600?
