The two equations for which the given number of fist is satisfied when x = 8 is plugged in are:
<span>P(x) = 13x^2 – 10x + 350
and
</span><span>P(x) = 18x^2 + 10x + 300
Now, we can only decide which is correct if we have additional information, specifically if we know the number of fish initially. If it is 350, option B is correct and if it is 300 then option D is correct.</span>
