Final answer:
The correct answer is (a) 23,305.
Step-by-step explanation:
The question is asking to calculate the number of visitors to museums that were below or equal to the age of 55, given that 41% of the visitors were over the age of 55. Knowing that 41% represents 16,195 people, we can calculate the total number of visitors. If 41% is 16,195, then 100% (the total visitors) is 16,195 divided by 0.41, which equals 39,500.
Now, to find the number of visitors who were 55 or younger, we subtract the visitors over the age of 55 from the total. So, 39,500 total visitors minus 16,195 visitors over the age of 55 equals 23,305 visitors who are 55 or younger. Therefore, the correct answer is (a) 23,305.
