Explanation:
To determine how many people will attend this year's fair, we can find the percent increase of people each year:
From year 1 to year 2, (10,365 - 9,278)/9,278 = 11.7% increase
From year 2 to year 3, (12,128 - 10,365)/10,365 = 17.0% increase
From year 3 to year 4, (13,304 - 12,128)/12,128 = 9.7% increase
