Final answer:
The utility functions for Enrique and Sylvia are U=√(C)√(S), where C represents the amount of chocolate ice cream consumed and S represents the amount of strawberry ice cream consumed. Their preferences for ice cream flavors are reflected in these functions.
Step-by-step explanation:
The utility functions for both Enrique and Sylvia are U=√(C)√(S), where U represents the level of utility, C represents the amount of chocolate ice cream consumed, and S represents the amount of strawberry ice cream consumed.
The square root function reflects their preferences for ice cream flavors. This function implies that as they consume more chocolate or strawberry ice cream, their level of utility increases, but at a decreasing rate. In other words, they enjoy each additional scoop of ice cream, but the additional enjoyment diminishes with each additional scoop.
