(b)The price of x, px, is$1, the price of y, py, is $2, and A's income, I, is $12.
i.(1 point)Please prove that A's optimal consumption must be an interior solution .
ii.(1 point)Solve for A's optimal consumption bundle.(You could assume it to be an interior solution, even if you fail to provide a proof in the previous problem.)
iii.(2 points)Please derive A's demand function of commodity x, x(px), when py and I remain constant.
iv.(2 points)Suppose px increases from $1 to $2, while py and I remain the same. Please calculate the substition effect, (dx, dy), due to this change.
