B 11.2 Have a good day :)
Is 76.63 because:
If it is 5 or above, you give it one more point .
If it is 4 or below, you let it stay still.
Step-by-step explanation:
If the library surveyed 240 people and only 15% chose documentaries, then only 36 people chose documentaries and the other 204 chose something else other than documentaries. You had to get 15% into decimal form and to do that you move the "." in 15.0% left 2 places so you get 0.15. Then you multiply 240 by 0.15 and you get 36.
