Felix's utility is u(x, y) = xy while Maria's utility is u(x, y) = x + y. Felix has an initial endowment of (Wx, Wy)=(10, 16) and Maria has an endowment of (Wx, Wy )=(10, 10). If px = 1, find the equilibrium demand for Felix and Maria for good x and y in terms py. Assuming Walras' Law is satisfied, solve for Py
