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.
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
