Solution
To predict the number of people Sam can take to the movies for $80, we need to find the cost per person.
From the table, we can see that the cost for 4 people is 64, and for 9 people is $72.
Let's calculate the cost per person for each group:
- For 4 people: 9 per person
- For 8 people: 8 per person
- For 9 people: 8 per person
We can see that the cost per person is not always the same. It's 8 per person for groups of 8 and 9.
However, since the cost per person for the larger groups (8 and 9 people) is 80.
So, 8 per person = 10 people
Therefore, Sam can take approximately 10 people to the movies for $80.
