Suppose the demand function for good x is given as: Qd=−1.1Px+0.7Py−0.5Pz+0.025M−0.05T where Px is the price of good x,Py is the price of good y,Pz is the price of good z, and M is consumer income. Suppose that Py=20,Pz=2,M=40 and T=100. What is the value of the constant (C) if the demand function is rewritten as: Qd=C−1.1Px
