Family of exponential value had equations of the form y = a *b^x … they can be used to model exponential growth or decay.

On January 3, 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 has 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 Checkersville? (need to show work and explain steps.)
