Since we have given that

According to the 2000 U.S. census, 7 out of every 25 homes are heated by electricity.

At this rate, we need to find the number of homes in a community of 12000 would be heated by electricity.

Let the number of homes in a community would be heated by electricity be x.

Since there is a direct variation,

So, it becomes,

Hence, there are 3360 homes in a community of 12000 would be heated by electricity.
