Answer

Answer:

725

Explanation:

Step1: Set up proportion

Let $x$ be the total zebra population. The proportion is $\frac{25}{x}=\frac{18}{522}$.

Step2: Cross - multiply

$18x = 25\times522$.

Step3: Calculate right - hand side

$25\times522=13050$. So, $18x = 13050$.

Step4: Solve for $x$

$x=\frac{13050}{18}=725$.
