The bird population on an island is declining at a rate of 2.2% per year. The population was 3500 in the year 2016. What will be the population in the year 2022?

Respuesta :

Answer:

3,063

Step-by-step explanation:

To find the population in a future year, use the formula:

[tex]A = P (1+/-r)^t[/tex]

where A is the amount, p is the starting population, r is 2.2% or 0.022, and t is the number of years after 2016.

Since the population is decreasing it is subtraction. Here we are finding A, P =3500, r=0.022, and t=6.

[tex]A = P (1-r)^t\\A = 3500 (1-0.022)^6\\A=3500(0.978)^6\\A=3,063[/tex]
