Answer:
238
Step-by-step explanation:
multiply 210 visitors by the number of the days of the week
210*6 = 1,260
add to it the visitors of Sundays which is 406
1,260*406=1,666
to know the average of visitors daily, divide the results by 7 days
1,666 / 7 = 238 visitors, is the daily average visitors.
