To determine the total number of cell phone subscribers that were in Centerville in 2020 is 5,928,227 people.
<u>Given the following data:</u>
- Number of subscribers = 285
- Percentage increase = 65%
Increment rate = 165% = 1.65
To determine the total number of cell phone subscribers that were in Centerville in 2020:
First of all, we would calculate the difference in years:
Year = 20 years
Mathematically, the growth rate of cell phone subscribers that were in Centerville in 2020 is given by the formula:
Substituting the given parameters into the formula, we have;
Subscribers = 5,928,227 people.

Formula for exponential growth is:
A = P(1+r)^t
Where A is the resulting amount, P is the initial value, r is the rate, and t is the time passed.
Filling this out for this situation gets you:
13400 = 10000(1+r)^6
Solving for r:
Divide 13400 by 10000
1.34 = (1+r)^6
Take the 6th root of both sides...
1 + r = 1.05
No more work is needed, since you aren’t solving for r.
Full equation:
V = 10000(1.05)^t
Answer C is correct
Answer:
g > 2t , 15 t + 9g >500 are the inequalities which can be used to find the value of g and t.
Step-by-step explanation:
Earning at grocery store = $9 per hour
Earning as tutor = $15 per hour
Let the number of hours she tutors = t
and the number of hours she works at grocery store = g
Total earning she wants = $500
Now, the earning from tuition = 15 t
Earning from Grocery store= 9g
According to the question:
g > 2t
15 t + 9g >500
Hence, both the above inequalities can be used to find the value of g and t.

Vertical angles are equal
so
3x - 3 = 6(x - 10)
3x - 3 = 6x - 60
6x - 3x = - 3 + 60
3x = 57
x = 19
