Question

the mean number of people per day visiting a museum in July was 160. If 20 more people each day visited the museum in August, what was the mean number of people per day visiting in August?
620
180
160
640

Answer 1

Since the number of days in July and in August is the same, there is no need to work out on the total number per month.

The mean number of people per day in August = 160 + 20 = 180

Answer: 180

Answer 2

Answer:

  180

Step-by-step explanation:

160 + 20 = 180

When the same value is added to each member of a set, the mean increases by that value.
