Answer

Answer:

950

Explanation:

Step1: Set up proportion

Let $x$ be the total elephant population. The proportion is $\frac{65}{x}=\frac{39}{570}$.

Step2: Cross - multiply

$39x = 65\times570$.

Step3: Calculate right - hand side

$65\times570 = 37050$, so $39x=37050$.

Step4: Solve for $x$

$x=\frac{37050}{39}=950$.
