Assume that the pizza market consists of two firms, Conan's and Pizza Hut. The price of a Conan pizza is denoted by Pc and the price of a Pizza Hut Pizza is Ph. Both sellers have a marginal cost of $5 for another pizza. The demand curves facing the two firms are: Conan ("c"): Qc = 500-35Pc + 20Ph Pizza Hut ("h"): Qh = 625-41Ph+26Pc. 1. Calculate the equilibrium prices. Pl(c)=(Pc-5)(500-35Pc+20Ph) dPi(c)/dPc=675-70Pc+20Ph=0 70PC-20Ph=675 P c=13.78 Pi(h)=(Ph-5)(625-41 Ph+26Pc) dpi(h)/dPh=830-82Ph+26Pc=0 -26Pc+82Ph=830 Ph=14.49 lalu
