Final answer:
The total number of students who participated in activities was 200. Out of those, 108 students went swimming, which is 54% of the total participants, though this option was not provided in the original question's choices.
Step-by-step explanation:
To find what percent of the students went swimming during reward day, we first need to know the total number of students who participated in any activity. The total is the sum of the students who played kickball, sang karaoke, and went swimming. Therefore, we calculate the total as follows:
- Students who played kickball: 57
- Students who sang karaoke: 35
- Students who went swimming: 108
Add these numbers together to find the total number of participating students:
57 + 35 + 108 = 200
Now, to find the percent of students who went swimming, we divide the number of students who went swimming by the total number of students, and then multiply by 100 to get the percentage:
(108 / 200) Ă— 100 = 54%
Since 54% is not one of the provided options, it might indicate that there's a typo in the provided options or the question itself. However, based on our calculation, 54% of the students went swimming.
