12500 people went to fair
<h3><u>Solution:</u></h3>
Given that at the county fair , 12% of the people who attended received free water bottles
1,500 people received free water bottles
To find: number of peoples went to fair
Let "a" be the number of peoples went to fair
From given information,
12% of the people who attended received free water bottles and 1,500 people received free water bottles
Which means 12% of total people is equal to 1500
12% of total people = 1500
12 % of "a" = 1500

Thus 12500 people went to fair
