Recall Lina from Q4.A and Q5.A, who obtains utility from books, x, and computers, y. Her preferences can be represented using the following utility function U (x, y) = y+2vx, Suppose the price of y is py, the price of x is pr, and Lina's income is m. Recall further that we have shown that ach (Px, Py , U) = Dy N y" (Px, Py, U) = U - 2Py Px e (Px, Py, U) = PU - Py Px whenever (Px, Py, U) is such that xh and y" above are both positive. Suppose we also knew that Ord am = 0. Use the Slutsky equation to calculate ox" apx
