The histogram shows the ages of the volunteers who cleaned up a beach.

what percent of the volunteers was at least 15 years old but no more than 24 years old?

The answer is 29.03%. because there are 2 people who are 15-19 and there are 7 people between 20-24. 7+2=9. and there are a total of 31 people. so 9 out 31 as a percent is 29.03%. hope this helps. please give me a brainliest
