For the demand function d(x) and supply function s(X), complete the following. d(x) = 900e0-02X, s(x) = 300 300e0-04X (a) Find the market demand (the positive value ofx at which the demand function intersects the supply function). (Round your answer to two decimal places.) (b) Find the consumers' surplus at the market demand found in part (a).
