To find the percentage of 7th graders who play bass in the School of Rock, you need to divide the number of 7th graders who play bass by the total number of 7th graders, and then multiply by 100 to convert it to a percentage.
From the data provided:
- Number of 7th graders who play bass = 11
- Total number of 7th graders = Guitar + Bass + Drums + Keyboard for 7th grade = 14 + 11 + 15 + 18 = 58
Now, calculate the percentage:
\[
\text{Percentage of 7th graders who play bass} = \left( \frac{11}{58} \right) \times 100
\]
\[
= \left( 0.1896551724 \right) \times 100 \approx 18.97
\]
Rounding to the nearest whole number percent, we get:
\[
\approx 19\%
\]
Thus, approximately 19% of the 7th graders at the School of Rock play bass.
