For question 2, how did you find the contract curve for the following question:

Suppose there are two consumers A and B. There are two goods X and Y. There is a TOTAL of 12 units of X and 12 Units of Y. Consumers utility function is given by:

UA(X,Y)= 3X + Y

UB(X,Y) = X*Y

Using an Edgeworth Box, illustrate the contract curve.
