Question

The flat population on an island is declining at a rate of 1.7% per year the population was 4600 in the year 2016 which answer is the best prediction of the population in the year 2023

Answer 1

4,080

Explanation:

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

`A = P (1+/-r)^t`

where A is the amount, p is the starting population, r is 1.7% or 0.017, and t is the number of years after 2016.

Since the population is decreasing it is subtraction. Here we are finding A, P =4600, r=0.017, and t=7.

`A = P (1-r)^t\\A = 4600 (1-0.017)^7\\A=4600(0.983)^7\\A=4,080`
