Answer:
C.32%
Explanation:
look at the column for grades 9-10 and add all of the different band preferences together: 40 + 30 + 55 = 125. Now, to find the percentage for rap music, divide the number of students for rap music by the total number of students in that grade group. 40 ÷ 125 = 0.32. Multiply by 100 to give it as a percentage. 0.32 × 100 = 32%
