The Population of a town increased by 80% in 5 years. If the population is currently 18,000, find the population of this town 5 years agao. (Round to the nearest whole, if necessary).
please send formula of this equation
Let X be the population 5 years ago.
X*(1.8) = 18,000
X = 10,000
Where does the 1.8x come from? Can you break that down?
To find the population of the town 5 years ago, we need to calculate what the population was before it increased by 80% in the span of 5 years.
Let's denote the population 5 years ago as P. We know that the population increased by 80% in 5 years, which means the current population is equal to 100% + 80% = 180% of the population 5 years ago.
So we can set up the equation:
180% = P
To solve for P, we can divide both sides of the equation by 180%:
P = 180% / 100% * (currently 18,000)
Now we can substitute the current population value into the equation and solve for P:
P = 180% / 100% * (18,000)
P = 1.8 * 18,000
P = 32,400
Therefore, the population of the town 5 years ago was approximately 32,400.
Let x = the original population of the town.
1.8x = 18,000
