The mean number of people per day visiting a museum in july was 120. if 20 more people each day visited the museum in august, what was the mean number of people per day visiting in august? a. 620 b. 140 c. 120 d. 640

The correct answer is 140 because the mean, average, number from July per day represents how many people would have visited each day if they were all even.

If there were 20 more people each day in August, the mean would be 140. This would represent how many people visited each day.
