Answer/Step-by-step explanation:
Part A:
![Key:\left[1 Adult = 4 Student]](https://tex.z-dn.net/?f=Key%3A%5Cleft%5B1%20Adult%20%3D%204%20Student%5D)

<u> 12 Student = 3 Adult</u>
<u>24 Student = 6 Adult</u>
<u>40 Student = 10 Adult</u>

Each book weighs 0.53 pounds when you round to the hundredths . This is because each book weighs the same and the stack of five weighs 9.5 pounds. Now, you divide 5 by 9.5 you get 0.52631579… and when you round the the hundredths you get 0.53
(X * y) + 9
Xy + 9
you can't reduce it further
