Question
The population in a small village is depleting. Over the last year, it has experienced a15% decrease and now has 340 resident How many people lived in the town one yearago?
Solution
To find the original population before the decrease, we need to understand that the current population represents 85% of the original population (because it has decreased by 15%).
We can set up the equation like this:
0.85 * Original Population = Current Population
Substitute the given current population into the equation:
0.85 * Original Population = 340
To solve for the Original Population, divide both sides of the equation by 0.85:
Original Population = 340 / 0.85
When you do the division, you find that the Original Population was approximately 400.
So, there were about 400 residents in the village one year ago.
