To find the total number of students who participated in the survey about whether they like rock music, we can look at the totals for each grade.
From the table:
- Total for Seventh Grade = 263
- Total for Eighth Grade = 275
Now, we add these two totals together:
263 (Seventh Grade) + 275 (Eighth Grade) = 538
Thus, the total number of students who participated in the survey is 538.
The correct response is:
538
