Question

This histogram shows the numbers of people who volunteered for community service and the number of hours they worked.

How many volunteers worked more than 10 hours?
25
60
75
85

Answer 1

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! =)
