In 2008, there were 285 cell phone subscribers in the small town of Berrydale. The number of subscribers increased by 75% per year after 2008. How many cell phone subscribers were in Berrydale in 2017?

Answer 1

Explanation:

`F=I(1.75^t)\\ \\ F=285(1.75)^(y-2008)\\ \\ F=285(1.75)^(2017-2008)\\ \\ F=285(1.75)^9\\ \\ F=43871.99\\ \\ F\approx 43872`
