Question 882859: A population increased 20% up to 1,450. What was the population before the increase?
Answer by JulietG(1812) (Show Source): You can put this solution on YOUR website!
Population (x) + .20 x = 1450
1.2x = 1450
Divide each side by 1.2
x = 1208.22 (or 1209; can't have a partial person)
.
Let's work it backward to prove.
A town has 1209 people.
Its population increases by 20%
1209 * .2 = 241.8 (242)
1209 + 242 = 1451 (answer is different due to rounding)
