You just said that "the same number of people visited each day",
so there's no "about" about it. It has to be an exact number.
Each day, (2744)/(14) = 196 people visited.
702 can not be written as the product of 2 prime numbers, because if you divide 702 by 2 then you get 351 and that is not a prime number. Therefore 702 is a prime number.
It is called a consistent dependent system
20,000 will be the population 40 years from now.
