Suppose Qxd = 10,000 - 2 Px + 3 Py - 4.5M, where Px = $100, Py = $50, and M = $2,000.
Use this information to answer the following three parts of question 6.
a. For this demand equation, what is the P intercept?
b. For this demand equation, what is the Q intercept?
c. Is Good X normal good or an inferior good?
d. If M changes to $1500, how much does Qd of X change?
e. Are Good X and Good Y substitutes or complements? How do you know?
