Answer:
Choise B..... 38.8
Step-by-step explanation:
trust
The input was one square so multiplied 2 would be 2 squares which is shown on both function machines. Then if you add 5 to the output you can see it because the blue part of the output is shown as a whole instead of 5 parts on the second function machine, so the value is still the same.
Ok I can help you on number 5 and 6. Sorry I dont understand number 7. You are correct on number six. There is not enough information because they do not say how many are 12 and how many are younger than 12. So on number 5 you would take 67 and divide it by 5. That is 13.4 so your answer for number 5 would be 13.4. Hope this helps!
