Best ResponseYou've already chosen the best response.2Firstly, do you know how to read this kind of graph? In other words, how many students babysat for 0 to 3 hours? How many for 47 hours?

Best ResponseYou've already chosen the best response.2Correct! Ok, now the next step is this: how many students were included in the survey? Well, that's easy  just add them all up. :)

Best ResponseYou've already chosen the best response.2You're welcome. But that's the first part of the problem. There is still one part remaining! >What percentage of the students surveyed babysat for at most three hours last weekend? That, too, should be easy. "babysat for AT MOST" three hours means only those who did 0 to 3 hrs. So take that number (the 03 hours) and divide it by 90 , the multiply by 100. That's your percent. :)
