The value, v(m), of a comic book m months after publication has an average rate of change of -0.04 between m = 36 and m
= 60. which statement must be true?
the value of the comic book decreased by a total of $0.04 between m = 36 and m = 60.
the value of the comic book increased by a total of $0.04 between m = 36 and m = 60.
the value of the comic book decreased by an average of $0.04 each month between m = 36 and m = 60.
the value of the comic book increased by an average of $0.04 each month between m = 36 and m = 60.

I believe the correct answer is C. The value of the comic book decreased by an average of $0.04 each month between m = 36 and m = 60.

Step-by-step explanation:

Option C.

Step-by-step explanation:

Let as consider V(m) represents the value of a comic book m months after publication.

It is given that between m = 36 and m= 60 the average rate of change in V(m) is -0.04.

Average rate of change represents the average change in the function for each month.

Negative sign of rate of change represents the negative change in the value of function.

The average rate of change is -0.04. So, the value of the comic book decreased by an average of $0.04 each month between m = 36 and m = 60.

Therefore, the correct option is C.
