Answer 1

Answer:

P ≥ 12

Explanation:

The equation that models the population is:

$P(t)=12\times3^{0.498t}$

At t=0 (Initially):

$\begin{gathered} P(0)=12\times3^{0.498\times0} \\ =12\times1 \\ =12 \end{gathered}$

Since we are told that the population of fruit flies increases, it means that the population cannot be less than 12.
