Answer: Jessica is correct

==================================================

Explanation:

  • Antonio is not correct because 3 cubed is not 9. Instead, it's 3^3 = 27. Note that 3^3 = 3*3*3 = 27. Another example would be 4^3 = 4*4*4 = 64. The good news is that he has the correct starting expression because the r^3+9 portion is the sum of r cubed and 9, then we double it.
  • Jessica is correct. She has the correct starting expression and has evaluated 3^3 correctly. Also, the final answer 72 is correct as well.
  • Maria doesn't have the correct starting expression.
  • The same goes for Mark. His starting expression isn't correct.

Solution

Given the population function to be;

P(t)=\frac{250t}{t+25}

When P(t) = 150

\begin{gathered} \Rightarrow\frac{250t}{t+25}=150 \\  \\ \Rightarrow250t=150(t+25) \\  \\ \Rightarrow250t=150t+3750 \\  \\ \Rightarrow250t-150t=3750 \\  \\ \Rightarrow100t=3750 \\  \\ \Rightarrow t=37.5\approx38 \end{gathered}

1803 + 38 = 1841.
