Problem 2: Brian wants to use his recent knowledge of utility to develop his own utility function for how many hours he should study for future tests. He mainly cares about two attributes: the number of hours he studies (x), and the mark (out of 100) that he gets (y). His research of utility functions shows that when a decision maker has to decide based on more than one attribute, a multi-linear multi-attribute utility function can be developed. This function follows the form U(x, y) = kxUx(x) + kyUy(y) + (1 − k¸-ky)Ux(x)Uy(y), where Ux(x) and Uy(y), are independent utility functions for attribute x and attribute y, and kx and ky are constants. If Brian just considers the number of hours he studies, he believes his utility function for the x² number of hours he studies is: Ux(x): = 1-: where 0 ≤ x ≤ 4. If Brian just considers the 16 mark he gets, his utility function is: Uy(y) = where 0 ≤ y ≤ 100. Brian is indifferent between (i) studying 0 hours and getting a mark of 49 and (ii) studying 4 hours and getting a y 100'
