Answer
$3000$
Work Step by Step
We are given the function $ f(x)=\dfrac{150 x+120}{0.05+1}$
We see that $ n=m $; therefore, the line $ y=\dfrac{a_n}{b_n}$ is the horizontal asymptote of the graph.
The horizontal asymptote is : $\dfrac{150}{0.05}=3000$
This implies that a maximum of $3000$ bass can live in the lake.
