Answer :
Answer:
approximately 19,764,459 cell phone owners in 2025
Step-by-step explanation:
We can solve this problem using the exponential growth formula:
A = P(r)^t
Where:
a = final amount
p = principal amount
r = rate
t = time
In this case, our values are:
a = ?
p = 285
r = 1.45
t = 30
Substitute the values in and solve for A.
A = P(r)^t
A = 285(1.45)^30
A = 19764458.81
round to nearest whole number since you can't have .81 of a person
19764458.81 ---> 19,764,459 cell phone owners
