Answer:

225 animals

Step-by-step explanation:

From the given information:

\dfrac{dA}{dt} = ( \dfrac{A}{1125}) (450 - A)

\dfrac{dA}{dt} = \dfrac{450A - A^2}{1125}

For a population increasing most rapidly; we have:

(\dfrac{dA}{dt} \implies max = A')

Thus; for \dfrac{d}{dA} ( \dfrac{dA}{dt}) \implies \dfrac{450-2A}{1125}

\dfrac{dA'}{dA} \implies 0  \\ \\   \\ A = 225
