The following function gives the total cost of a water bill dependent on the amount of time (t) in hours that the water runs.
C(t)=3(0.24)t
A. What does C(t) represent in the context of this problem?
B. What does t = 7 represent in the context of this problem?
C. What does C(7) mean in the context of this problem?
D. Does finding C(-4) make sense in the context of this problem?

A. C(t) represents the total cost of the water bill in dollars.
B. t = 7 represents the amount of time in hours that the water runs.
C. C(7) means plugging in t=7 into the function to find the total cost of the water bill after the water has run for 7 hours.
D. No, finding C(-4) does not make sense in the context of this problem because time cannot be negative.
