AS FAST AS POSSIBLE PLEASE! PROBLEM 2 PART 2 

A consumer has utility function
ху
u(x, y) =
x+ y
%3D
for two goods, where x >0 denotes the amount of X consumed and y> 0 the amount of Y
consumed. Each unit of X costs p dollars, each unit of Y costs q dollars, and the consumer has a
budget for X and Y of M dollars.
Suppose that U(M) = u(x',y') is the maximum achievable utility. Find an explicit
expression for U in terms of p, q and M, simplify your answer as much as possible. Find
ƏM
and verify that it is equal to 2".
