D

Step-by-step explanation:

Just by looking at the data, you cannot answer A, B, or C because they are asking for who. There is no information on the data on WHO each piece of data is referring to. You can only answer D, which asks for HOW MANY. You can count how many 8s there are and answer the question.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
