In a survey of 800 students,
548 said they liked pizza for lunch, 173 said they like
hamburgers, and 79 said they like sloppy joes. Draw bar
diagrams and write equations to find how many more
students liked pizza than liked hamburgers and sloppy joes
combined.

The bar graph shows in the attachment bases on frequency distribution equation for Lunch is 68:22:10 which mean the equation is 68x+22y+10 is the combined information.

Step-by-step explanation:

Column lunch and row had Pizza,Hamburger and Sloppy joe.The total 548,173 and 79 total to 800 students.Creating a bar graph series name is lunch and series value is pizza....hamburgers and sloppy joes.Frequency distribution basis on percentage involves...Number of categories/ Total number of students.68:22:10 so the distribution has about 68 percent of people....Eat pizza more than hamburger and sloppy joes.Horizontal axis has about Pizza,Hamburger and Sloppy joes.
