Answer
Explanation:
Step1: Find number of volunteers in 15 - 24 age range
The number of volunteers in 15 - 19 age - group is 2 and in 20 - 24 age - group is 7. So the number of volunteers in 15 - 24 age range is $2 + 7=9$.
Step2: Find total number of volunteers
$3+2 + 7+8+5+5=30$.
Step3: Calculate the percentage
The percentage is $\frac{9}{30}\times100% = 30%$.
Answer:
30%
