Given that there are currently 95 million fruit flies on earth and that the population is decreasing at a rate of 4.35% per year, we can find the number of fruit flies there will be in 14 years below.

Step-by-step explanation

We can use the exponential decay model below


\begin{gathered} y=ab^x=a(1-r)^x \\ where\text{ r is rate and a is initial population and x is time} \end{gathered}

Therefore;


y=95000000(1-(4.35)/(100))_^^(14)==95000000\cdot\:0.9565^(14)=50969837.19305

Answer: Approximately 50969837 fruit flies
