riadik2000 [5.3K]

Answer:

The average number of visitors per day is 272.

Step-by-step explanation:

Total number of visitors in the zoo in a year =  98,464

Now,we know that  1 YEAR = 365 DAYS

Also, the zoo was closed on thanksgiving, Christmas, and New Year's Eve

So, the Number of days zoo was open = Total Days in  year -  3 days

= 365 - 3 = 362 days

⇒Number of visitors in  362 days =  98,464

So, \textrm{Number of visitor per day} =  \frac{\textrm{Total number of visitors in 352 days}}{\textrm{352 days}}

= \frac{98,464}{362}  = 272

or, the number of people visiting per day is 272.

Hence,  the average number of visitors per day is 272.
