Question 1: Suppose there are 90 consumers in the market with two goods x and y. There are two types of individuals A and B. 60 of the consumers are type A and the 30 of them are type B. Type A consumers have a utility function of u(x,y)=x 1/3
y 1/3
and each of them has an income of m A
​
. Type B consumers have a utility function of u(x,y)=x 2/3
y 1/3
and each of them has an income of m B
