Quasi-linear Utility An individual has utility function U(x,y)=u(x)+y for some function u(x) which also obeys all of our typical assumptions for a rational utility function. In reality, though, x is a discrete item, such that the individual's consumption can only be x=0 or x=1. For convenience, assume that p y
​
=1. a) Derive a mathematical expression for the range of values for p x
​
that would lead to the individual choosing x=1. (5 points) b) What is the indirect utility function associated with this individual?
