Answer 1

15,000

Explanation:

The population of a city has increased by 26% since it was last measured. If the current population is 18,900 , what was the previous population?

increase of 26% means the current population is 126% of the previous.

126% = 1.26

18,900 = 1.26x

divide both sides by 1.26:

18,900/1.26 = 1.26x/1.26

x = 15,000

previous population was 15,000
