Question

I am so confused i need help

Answer 1

Answer:

40

Step-by-step explanation:

There is enough information, so D is not an answer.

10 is far to low. The number is roughly 40. So A is not the answer.

16/20 = .80 that recommended the tooth paste. If you stopped there, 40 would be your answer.  But they took one more survey.

24/30 = .80

So both groups come back with an amount that = 0.8

That means that you should pick 40 as your answer.

Answer 2

I believe The answer is B 40
