There are currently 95 million fruit flies on earth. the population is decreasing at a rate of 4.35% per year. how many fruit flies will there be in 14 years

Respuesta :

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.

Explanation

We can use the exponential decay model below

[tex]\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}[/tex]

Therefore;

[tex]y=95000000(1-\frac{4.35}{100})_^^{14}==95000000\cdot\:0.9565^{14}=50969837.19305[/tex]

Answer: Approximately 50969837 fruit flies
