Assume an hypothetical consumer faced by the following utility function; U=X^2Y ( squared times y). After a bad harvest and thus bad economic conditions, the price of good X increases from Ksh.4.2 to Ksh. 4.8, while the price of good Y which was ksh. 4 increased to ksh.5. The income of the consumer was ksh. 30 before and after the good harvest. Calculate the CV and EV.
