Answer to Question #296911 in Civil and Environmental Engineering for James

Question

According to the data listed at the Philippine Statistics Authority, the Philippine total

population reached 4 billion persons in year 2020 and was then increasing at the rate of 250

thousand persons each day. Assuming that natural population growth at this rate continues, what

will be the population at year 2060?

Answer 1

4 billion = 2020 

Increase rate= 250,000 per day

2060=?

Population growth= x(t) = x0 × (1 + r) t

Initial Population (X0)=4000000000

Rate of Growth (%) =(r)9.125

# of years (t)=40

x(t)=40,000,000,000$\times$ (1+9.125)40

x(t)=40,000,000,000$\times$ 10.125$\times$ 40

x(t)= 131531647490.14851

Population at year 2060= 131531647490 people.
