Step-by-step explanation:
The number of cell phone subscribers in Arlington, in t years after 1985, can be modeled by the following equation.
And which N(0) is the number of subscribers in 1985 and r is the rate it increases per year, as a decimal.

So
Find the number of subscribers in 2008.
2008 is 2008-1985 = 23 years after 1985. So we have to find N(23).
The number of subscribers in 2008 is 110,845,988
