            double tipRate;
            double tip;
            const double LOWRATE = 0.10;

            const double DINNERSTEP = 10.00;

            Console.Write("   Price");
            for (tipRate = LOWRATE; tipRate <= MAXRATE; tipRate += TIPSTEP)
                Console.Write("{0, 8}", tipRate.ToString("F"));
