Answer 1

The answer to your question is 70.4%

Explanation:

Data

Year Population

2009 2.7

2017 4.6

Process

To solve this problem use proportions and cross multiplication. Consider the population of 2009 is 100%.

2.7 ------------------------- 100%

4.6 ------------------------ x

x = (4.6 x 100) / 2.7

x = 460/2.7

x = 170.4%

-Substract 100% from the result.

Percent change = 170.4 - 100

= 70.4%
