Consider an individual whose utility function is U = X0.5Y0.5. If the individual consumes 1 unit of X and 4 units of Y, then she will experience some level of utility. If the individual instead consumes 2 units of Y, how much of good X must she consume in order to attain the level of utility associated with 1 unit of X and 4 units of Y?
