Barbara Oconnor · Answer 1

The correct answer is A, there were the same number of tickets sold on the fourth and tenth day. The average rate of change is 0 for the specified interval, which means that there was a constant number of tickets sold on the fourth and tenth day.

since the rate of change is 0 the same number of tickets was sold on the 10th day as the 4th day, the rate of change didn't change.
