Question

the population of a city has increased by 35% since it was last measured. if the current population is 29,700, what was the previous population?

Explanation:

Step1: Let previous population be $x$.

The current population is $x$ plus 35% of $x$, so $29700=x + 0.35x$.

Step2: Combine like - terms.

$29700=(1 + 0.35)x=1.35x$.

Step3: Solve for $x$.

$x=\frac{29700}{1.35}$.
$x = 22000$.

Answer:

22000
