I Have Been Saving My Money to Buy a New $\$ 22,000$

Multiple Choice

I have been saving my money to buy a new car. I know that I want to buy a Prius and that it will cost about $\$ 22,000$ . My refrigerator has been malfunctioning too, so any left over money will go towards repairs. My utility function can be written as $U(x, p, \varepsilon) =x+z(p, \varepsilon)$ , where $\mathrm{x}=1$ if $\mathrm{I}$ buy the Prius and 0 otherwise, $\mathrm{p}$ is the price of the Prius and $\varepsilon$ is my reference point. Which of the following functions for $z(p, \varepsilon)$ best describes the scenario above?

A) $z(p, \varepsilon) =(22,000-p)$ .
B) $z(p, \varepsilon) =|p-22,000|$ .
C) $z(p, e) =|x-p|$ .
D) $z(p, e) =(x-p) ^{2}$ .
