Math and the answer

Question

In a recent 10 year. The change in the number of visitors to amusement park was about 15,000 visitors what was the mean yearly change in the number of visitors

Answer 1

If 15,000 visitors came within ten years, the mean amount of visitors would be 1,500 visitors per year.

1500/10 years = x visitors/1 year

15,000(1 year) = x(10 years)

15,000/10 = mean number of visitors
