Answer provided by our tutors

motivated movers = (150+30x)                                      quick-pak moving = $80x           

x equals the # of hours                                                       x equals the # of hours

hours= price                                                                            hours= price

   1=$180                                                                                  1=$80

   2=$210                                                                                  2=$160

   3=$240                                                                                  3=240

   4=$270                                                                                  4=360

                                              150+30x<80x

                                                   -30x<+30x

                                                150<50x

                                                50x    50x
