b. write a second function to represent the cost of membership of the club raises its membership fee to $30

c. describe the relation ship between the function from part A and B.

Answer 1

20 + 12x = y
20 represents the membership fee
12 represents the cost of each book
x represents the number of books
y represents the total costs of all books and membership cost

30 + 12x = y
30 represents the membership fee
12 represents the cost of each book
x represents the number of books
y represents the total costs of all books and membership cost

b. y= 30+12x
I hope this helps!
