50000 + 0.07x*50000>70000-0.04x*70000.
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.
50000 + 3500x > 70000 - 2800x
3500x + 2800x > 70000 - 50000
6300x > 20000
X > 3.17 yr.
