Answer:
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
