Final answer:
The percent of students who own cats is 10%.
Step-by-step explanation:
To find the percent of students who own cats, we need to divide the number of students who own cats by the total number of students in the survey and then multiply by 100. In this case, we have 30 students who own cats out of a total of 300 students. So, the percent of students who own cats is:
Percent of students who own cats = (Number of students who own cats / Total number of students) * 100
Percent of students who own cats = (30 / 300) * 100 = 10%
