A city has a population of 350,000. The population has decreased by 30% in the past ten years. What was the population of the city ten years ago?

Answer 1

Answer: The answer is 500,000.

Step-by-step explanation:

100% - 30%  = 70%

          x   =>    100%

350000   =>      70%

x = 350000*100% / 70%

x = 500000
