Statesville's population in 2010 was about 24,400, and was growing by about 1.2% each year. If this continues, what will Statesville's population be in 2019? [Round to the nearest person.]

Answer 1

To find the population of Statesville in 2019 we use the Exponential growth formula:

Exponential growth: N = NO x (1 + K)^t

N = the population for 2019

NO = Initial population = 24,400

k = growth rate = 1.2% or 0.012

t = number of years t = N - No = 2019 - 2010 = 9 t=9

1. Convet the growth rate to a decimal 1.2 divided by 100 = .012
2. Use the Growth formula to calculate the population for 2019

Growth Formula: N = NO x (1 + k)^t

(roundoff)

N = 24,400 x ( 1 + .012)^9 = 24,400 x (1.012)^9 = 24,400 x 1.113331796 = 27165.29583 = 27165

Solution:

Statesville population for 2019 = 27,265

I hope the mathematical calculations (step by step approach) was helpful. Please let me know if you require any more assistance. If anyone in my neighborhood is interested in setting up an in-person math tutoring session. I look forward to hearing from them. Have an amazing day. Doris H.
