Yes the number of slices of pizza is proportional to the number of people attending the party because the ratio of the number of slices to the number of people is constant (4/3) for each row.
Based on the information given, we need to determine if the number of slices of pizza needed is proportional to the number of people attending the party.
To do this, we can examine the table Ms. Albero made. If the ratio of the number of slices of pizza to the number of people is constant, then the number of slices is proportional to the number of people.
Let's analyze the table:
Number of People (attendees) | Number of Slices of Pizza
6 | 8
9 | 12
12 | 16
15 | 20
18 | 24
To check if the number of slices is proportional to the number of people, we can calculate the ratio of the number of slices to the number of people for each row in the table:
For the first row: 8 slices / 6 people = 4/3
For the second row: 12 slices / 9 people = 4/3
For the third row: 16 slices / 12 people = 4/3
For the fourth row: 20 slices / 15 people = 4/3
For the fifth row: 24 slices / 18 people = 4/3
Since the ratio is the same (4/3) for each row, we can conclude that the number of slices of pizza needed is proportional to the number of people attending the party.
The probable complete question could be" Ms. Albero decides to order pizza for her Student Council pizza party. She orders pizza for 18students. She made a table to show the number of slices of pizza needed for a certain number ofpeople. According to the table, is the number of slices proportional to the number of people attendingthe party?
