add up the heights of the first 3 bars to get your answer

3. iAmCool

Well, 5+10+25=40 .. then what?

4. iAmCool

40 is my answer?

5. jim_thompson5910

so there are 40 students who babysat for at most eleven hours there are 5+10+25+35 = 75 students total

6. iAmCool

So now I divide 40 by 75?

7. jim_thompson5910

so the percentage who babysat for at most eleven hours is (40/70)*100 = 57.1428% roughly

8. iAmCool

So 57% if rounded?

9. jim_thompson5910

yep

10. iAmCool

But why did you put 70 instead of 75.. :I

11. jim_thompson5910

oh my bad...i saw the 0 on 40 and thought it was 70, let me fix (40/75)*100 = 53.333%

12. jim_thompson5910

fixed

13. graydarl

75.........100% 40...........x% sox%=(40*100)/75 or (40/75)*100=53.33%
