Enter your answer in the box.

%

Answer 1

30%

Explanation:

Age No. of volunteers

10-14 3

15-19 2

20-24 7

25-29 8

30-34 5

35-39 5

Total no. of volunteers = 3+2+7+8+5+5 =30

Now we are supposed to find What percent of the volunteers was at least 15 years old but no more than 24 years old

15-19 2

20-24 7

So, total no. of volunteers was at least 15 years old but no more than 24 years old = 7+2=9

So, percentage of volunteers was at least 15 years old but no more than 24 years old:

=
`(9)/(30) * 100`

=
`30\%`

Hence 30 % of volunteers was t least 15 years old but no more than 24 years old.
