Answer:
Option C.
Step-by-step explanation:
This is a function because all of the numbers have a partner, and none of them have more than one. 
                                     Example of Not a Function
Function                                Not a Function
-4 to 5                                      <em> -4 to 5</em>                             <
9 to 7                                       <em> -4 to 3    </em>                          <
13 to 3                                       13 to 3                              ^
-7 to 5                                        9 to 7                               ^
                                                  -7 to 5                               ^
                                            Not a Function because of this
 
        
             
        
        
        
12/3 = 4
4 cars per hour
4 x 5 = $20
20 x 8 = $160 for 8 hrs

Answer:
y=x+5.99
Step-by-step explanation:
A poster and 2 comics cost $7.99
(2,7.99)
A poster and 11 comics cost $16.99.
(11,16.99)
Let y be the cost of package and x be the no. of comics
We will use two point slope form :
(x1,y1) = (2,7.99)
(x2,y2) = (11,16.99)
Formula : 
y-y1 = y2-y1/x2-x1(x-x1)
Substitute the values:
Hence a linear function rule that models the cost y of a package containing any number x of comic books is y=x+5.99
