[25] Besties, Sohail and Jimmy are binge-watching Twilight when the Covid lockdown starts. Owing to mobility restrictions, for a two-week period, they are shut off from the rest of society ( think of this as a deserted island situation). Although they are unable to produce anything, they are very fortunate and each of them has a supply of cookies (c) and Mountain Dew (d). Sohail has 4 cookies and 3 bottles of Mountain Dew, while Jimmy has 3 cookies and 4 bottles of Mountain Dew. Although they like the same products, they have different preferences over them; Sohail's utility function is U(c,d) = cd and Jimmy's utility function is U(c d) = 3cad. a.
