A population increases from 358 individuals to 403 individuals in a year. What is the percent change written as a decimal to the nearest thousandth?

The percent change = 0.126

Step-by-step explanation:

A population increases from 358 individuals to 403 individuals in a year.

The increase = 403 - 358 = 45 individuals

So, the percent change = increased amount/original amount

So, the percent change = 45/358 = 0.126 (to the nearest thousandth)

So, the percent change = 0.126

As a decimal = 0.126

As percentage = 12.6%
