a) The market research department of Lamex Enterprises has determined that the demand for good X is Q = 1,200 - 4 P+0.031-25PZ, where P is the price of good X, I is consumer income, and Pz is the price of good Z. Suppose that P = Ksh 6, I = Kshs 25,000, and Pz - Ksh15. (iii) At P = Ksh 6, compute the income elasticity of demand for good X.

Julian is interested in only two goods: good X and good Y and has M dollars to spend (and always spends it all). His uncle Paul is rich and he offered him 1000 dollars as a present but Julian did not take it and chose to just spend his own money. Julian's demand function for good X and the demand function for good Y are given respectively by XJ = 32800/(10Px + Py) and Y₁ = 3280/(10Px + Py). What is Julian's spending money "M"?
