From 1988 to 1989, the population of Col-
orado Springs increased by 5409, and that of
Wichita increased by 4640. In 1989, the pop-
ulation of Colorado Springs andWichita were
284482 and 297391, respectively.
-----
Springs growth: S(x) = 284482 + 5409x
---------------------
Wichita growth: W(x) = 297391 + 4640x
============================================
If the populations continue to increase at
the same rates, in what year will the popula-
tions of the two cities be the same?
-------
Solve S(x) = G(x) for "x":
284482 + 5409x = 297391 + 4640x
769x = 12909
x = 16.79 years
---
1989 + 16.79 = 2005.79
---
Year = 2006
