Question 20 4 points Saved One of the conditions for consumer equilibrium (in terms of Utility Maximization) can be expressed as follows: Oay = [-px/py] X + M/py O b.MUx = JU(x.y) / dx = MUy = QU(x,y) /dy O C. MRS = Ay/ Ax = px/py O d. MUYIpx = MUXIpy Question 19 4 points *Saved Suppose when the consumer's income rises by 100%, the consumer's consumption of good X falls by 1%.
