The question seems to be to fill out the table.

Fill out the givens first

  • 12 grade 8 students brought a lunch .

Copy the Table here. Keep filling it up as you go.

    Grade             Pack a Lunch             Buy a Lunch     Number

  •          7                                                                          50          
  •          8              12
  •          Number                                       44

First Step:          Find the grade 8s. They must number 80 - 50 = 30

Second Step:     Find the number of Grade 8s who Buy a lunch 30 - 12 = 18

Fill in these two steps.


    Grade             Pack a Lunch             Buy a Lunch     Number

  •          7                                                                          50          
  •          8              12                                18                     30
  •          Number                                      44

Step 3: Find the number of 7s who buy a lunch: 44 - 18 = 26

Step 4: Find the number of 7s who Pack a Lunch: 50 - 26 = 24

Step 5: Find the total number of students who Pack a Lunch: 12 + 24 =36

Record these three steps


Grade             Pack a Lunch             Buy a Lunch     Number

  •          7              24                               26                    50          
  •          8              12                                18                     30
  •          Number   36                              44                     80

Looks like this fills out the table and it is your answer.
