In a local election, 25,800 people voted. This was an increase of 5% over the last election. How many people voted in the last election? Round to the nearest whole person.

Let L be the amount of voters at the last election, and because the new vote-count of 25,800 people represents a 5% increase or 1.05, we can say that:

1.05%2F1+=+25800%2FL

1.05L = 25,800 ------- Cross-multiplying

L, or last amount = 25800%2F1.05 = 24571.42857, or ~highlight_green%2824572%29 voters.
