On January 1, 2010, Chessville has a population of 50,000 people. Chessville then enters a period of population growth. Its population increases 7% each year. On the same day, Checkersville had a population of 70,000 people. Checkersville starts to experience a population decline. Its population decreases 4% each year. During what year will the population of Chessville first exceed that a Checkersville? Show all of your work and explain your steps.

Any help would be great.

50000 + 3500x > 70000 - 2800x

3500x + 2800x > 70000 - 50000

6300x > 20000

X > 3.17 yr.

So the population of Chessville becomes greater than the population of Checkers-

ville during the 3rd yr.
