Answer:
112,547.095 million
Step-by-step explanation:
Data provided in the question
Population of a city in 2005 = 18,000
In the year 2010, the city population = 45,000
Now to find out the projected population for 2015 we use the exponential model

where
P(0) = Initial population
r = growth rate
t = time
e = natural log
So,

So


r ≈ 0.1833
Now

= 112,547.095 million
