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.
