Answer:
C
Step-by-step explanation:
The monthly fee is going to be $5 and she's playing for a month, so let's put that down-
5+
Now, we need to figure out how much she plays - since we don't know this, we put it as a letter, and since we're calculating the cost, we add this to the equation-
5+0.25*x
Therefor, the answer is C(x)=5+0.25x
If the plays for 4 hours, the equation would be 5+(0.25*4)
