Question

Given

Q1 = 150 - 3P1 + P2 + P3

Q2 = 180 + P1 - 4P2 + 2P3

Q3 = 200 + 2P1 + P2 - 5P3 and

TC = Q12 + Q1Q2 + 2Q22 + Q2Q3 + Q32 + Q1Q3

a) Find the inverse demand function P = f(Q) and use Cramer’s rule to solve for the critical value Q1 & the critical value Q2.
b)Use Cramer’s rule to solve for the critical value Q3.
c)Calculate the Hessian matrix. What is the value of |H3|? Based on the Hessian, what can you say about the profit?
