... implying 0.4 = d (18/ 13) and -0 .4 = -b (18/ 23). So d = 0.29 and b = 0.51. Next solve for c and a: S c = c + dP and Q D = a - bP, implying 13 = c + (0.29) (18) and 23 = a - (0.51) (18) . So c = 7.78 ... Q D = 23, E D = -b(P*/Q*) = -0 .05, and b = 0.06. Substituting for b, Q D = 23, and P = 18 in the demand equation gives 23 = a - 0.06 (18) , so that a = 24.08....
