I believe you answer would be 9+4x=c
9 is how much the cost for the first hour
4x is the 4 X the numbers of additional hours add
C is how much the cost is
all you need to the is the x
plug in the x to the problem and you should get your answer


I will give you an example 
let say he spent an hour over 
so that would be 4 more dollars he would have to pay


now you right out your problem
9+4x=c
we said he only went 1 hour over  so we will plug 1 in for x
9+4X1=c
now we are going to solve fo 4X1wich is 4
now you problem should look like this 
9+4=c 
add 9+4
now i will looklike this 
13=13
now check you answer


13-4=9
is this right 
yes it is 
so you woud do 9+4x=c to find what the total cost is 
 

hope this helps
