D. none of these
The total number of sixth graders who participated in the survey is 3+5+2=10, and the total number of seventh graders who participated in the survey is 6+3+1=10. Therefore, the total number of students who participated in the survey is 10+10=20.
So, the correct answer is B. 20.
To find the total number of students who participated in the survey, you need to add up the number of sixth graders and seventh graders for each activity.
For walking:
- Six sixth graders and seven seventh graders participated, totaling 6 + 7 = 13 students.
For biking:
- Five sixth graders and three seventh graders participated, totaling 5 + 3 = 8 students.
For skateboarding:
- Two sixth graders and one seventh grader participated, totaling 2 + 1 = 3 students.
To find the total number of students, you need to add up the number of students for each activity: 13 + 8 + 3 = 24.
Therefore, the correct answer is B. 20 students.
To find the total number of students who participated in the survey, you need to add the number of students from each grade level:
