Suppose Justin's preference over goods x and y remain unchanged over two periods, and he has $100 budget in each period. In the first period, the prices were given by p_x= 20 and p_y= 10, and he chose bundleA= (4,2); in the second period the prices were given by p_x = 10 and p_y= 20, and he chose bundle B = (2, 4). Is Justin's behavior consistent with the model we developed of rational consumer behavior? Explain.
