=+B. In exercise 15.2, you should have derived the aggregate demand function X D 1p2 5 250,000/p 2

from the presence of 10,000 consumers with tastes that can be represented by the utility function u1x, y2 5 10x 0.5 1 y. Suppose that this accurately characterizes the demand side of the market in the current problem. Suppose further that the market supply curve is given by the equation X

S 1p2 5 250,000p.
