The mean number of people per day visiting a museum in July was 160. If 20 more people each day visit the museum in August, what was the mean number of people visiting in August?

OpenStudy (anonymous):

So 4960 people visited in July. 20 more people means 20 x 31 = 620. 620 + 4960 = 5580. So find the mean from there.
