Question

In 1990 , there were 275 cell phone subscribers in the small town of Centerville. The number of subscribers increased by 80% per year after 199 How many cell phone subscribers were in Centerville in 2000 ? Round your answer to the nearest whole number.

Answer 1

In 2000, there were about 12052 cell phone subscribers in Centerville. This is calculated using the formula for exponential growth, where the initial number of subscribers was 275, the annual growth rate was 80%, and the time period was 10 years.

Step-by-step explanation:

This Math problem can be solved using the concept of exponential growth. Here, the initial amount (No) is 275, the growth rate (r) is 80% or 0.8 annually, and we are looking for the total number (N) of cell phone subscribers by the end of 2000, which is 10 years (t) from 1990.

The formula we use is N = No*(1 + r)^t. Substituting the numbers, we can calculate N = 275*(1 + 0.8)^10. After calculating, we find N = 12051.67, but since we cannot have a fraction of a cell phone subscriber, we round to the nearest whole number resulting in 12052 cell phone subscribers in Centerville by 2000.
