Answer 2

Answer: I think the answer is 24.5%.

Step-by-step explanation: Because there are 30% of people who live off campus, the rest live on campus, which is 70%. 65% of those living on campus have a part time job. 65% of 70 is 45.5. The rest of them who live on campus that don't have a
part time job, is 35, or 35%. 35% of 70 is 24.5. But because it asking how many people who live on campus don't have a part time job out of everyone, not just those who live on campus, the answer would be 24.5% of 100, or just 24.5%.
