Given that 136 students are in the cafeteria and the ratio of students buying lunch to those who brought their lunch is 3:10.

This means that for every 3 student buying lunch, there are 10 students who brought their lunch.

The number of students that brought their lunch is obtained as follows:

[tex] \frac{10}{3+10} \times136= \frac{10}{13} \times136= \frac{1,360}{13} \approx105\ students[/tex]
