                                print "level 1"
                                print 0
                elif val <= 3500 :
                                print "level 2"
                                print (val - 1600) * 0.05
                elif val <= 6500 :
                                print "level 3"
                                print (val - 3500) * 0.10 + (3500-1600) * 0.05
                else:
