In 2005, for each of the 14 million people present in a country, 0.028 were born and 0.008 died during the year.
r = 0.028 - 0.008 = 0.02
dt = 2015 - 2005 = 10 years
N = N2005 = 14 million
dN = change in population in 10 years

dN = 0.02 x 14 x 10
dN = 2.8 milliom
dN = N2015 - N2005
N2015 = dN + N2005
= 2.8 + 14
= 16.8 ≈ 17 million

Exponential Equation for Population Growth

The exponential equation for population growth is given by:

N(t) = N0e^(rt)

Where N(t) is the number of individuals at time t, N0 is the initial number of individuals, e is the mathematical constant equal to approximately 2.718, r is the growth rate, and t is the time elapsed.

Population Growth in 2005

Given that in 2005, for each of the 14 million people present in a country, 0.028 were born and 0.008 died during the year, we can calculate the growth rate as follows:

r = (birth rate - death rate) = (0.028 - 0.008) = 0.02

We can also determine the initial number of individuals as N0 = 14 million.

Using these values, we can write the exponential equation for population growth as:

N(t) = 14e^(0.02t)

Prediction for Population in 2015

To predict the number of people present in 2015, we need to substitute t = 10 years into the exponential equation and solve for N(10):

N(10) = 14e^(0.02*10) = 17.81 million

Therefore, the predicted number of people present in 2015 is 17 million, which corresponds to option B.
