$3.30

Step-by-step explanation:

                                  19.50

                   19.50 divided by 2 is 9.75

      represents burgers                   represents hotdogs

  9.75 dived by 4 is 2.43               9.75 dived by 3 is 3.25

              2.43                                                   3.25  

              2.43                                                   3.25

              2.43                                                   3.25

              2.43                          

                                    33.50

                 33.50 divided by 2 is 16.75

represents cheeseburgers        represents hot dogs

16.75 divided by 7 is 2.39      16.75 divided by 5 is 3.35

               2.39                                          3.35

               2.39                                          3.35

               2.39                                          3.35

               2.39                                          3.35

               2.39                                          3.35

               2.39  

               2.39  

so the hot dog prices were 3.25 and 3.35 sooo.. we round them together its $3.30
