Question

Suppose the population of a certain city is 3306 thousand. It is expected to decrease to 2523 thousand in 50 years. Find the percent decrease.

Answer 1

difference between them/3306x100=ans.

Answer 2

Percent change = 100 x [(final population) - (initial population)] / (initial population)

 

initial population = 3735000

final population = 3043000

 

percent change = 100 x (3043000 - 3735000)/3735000 = -18.53%

 

The negative number means the population decreased by 18.53%.
