This histogram shows the numbers of people who volunteered for community service and the number of hours they worked.
Inga [223]
The correct answer is :85

You can find this out because you would count by fives so : 5, 10, 15, 20, 25 so there are 25 volunteers in the 11-15 hours worked so you would add that to the 21-25 also known as 10 hours worked you also have to add 16-20 also known as 50 so add all that and you get  50 + 25 + 10 = 85

So it's 85
I hope this helped! =)
