Final answer:
The college's constraints for accepting students are 0 < x ≤ 100 for out-of-state students and 0 < y ≤ 300 for in-state students, with the in-state students being three times the number of out-of-state students. The correct answer is option 1.
Step-by-step explanation:
The constraints for the number of students that a college is accepting are based on the conditions provided: the college plans to accept three times as many in-state students as out-of-state students, and they only have space to accept 100 out-of-state students.
With x defined as the number of out-of-state students and y as the number of in-state students, we can establish the constraints for x and y. Given that the college can only accept up to 100 out-of-state students, which means 0 < x ≤ 100. Since they accept three times as many in-state students as out-of-state, we can also determine that 0 < y ≤ 300 because the maximum number of in-state students (y) would be 300 if there are 100 out-of-state students (x).
Therefore, the correct constraints representing the incoming students at the college would be: 0 < x ≤ 100 and 0 < y ≤ 300. Hence, the correct option is 0 < x ≤ 100 and 0 < y ≤ 300.
