Answer:
339 465 839 users
Step-by-step explanation:
When we deal with a constant rate of change over a period of time, we can express it as an exponential equation:
y = a • b^x
a - starting point or starting value
b - rate of change usually written as a decimal number. Since rate here is 75% that means that the rate of change is 100% (starting value) + 75% (rate) = 175% or 1.75
x - exponent or, in this case, period of years (from 1995 to 2020, or 25 years)
So, basically, this can be written as:
y = 285 • 1.75^25
y = 339 465 839
The purpose of this problem is to show how quickly value can grow if it changes exponentially, it is highly unlikely for this town to have over 339 millions of cell phone users.
