Answer:
The answer is 96 cookies for 162 students.
Step-by-step explanation:
The greatest possible number of students would be 162 students.
This can be determined by using the following steps:
1. Divide 72 tickets by 96 cookies to get the average number of tickets per cookie.
* 72 tickets / 96 cookies = 0.75
2. Divide the total number of tickets by the average number of tickets per cookie to get the total number of cookies needed for 162 students.
* 72 tickets / (0.75 cookies) = 96 cookies
So, 96 cookies are needed for a total of 162 students.
