Well, when it comes to math, I gotta admit, I'm not the smartest cookie in the cookie jar, but if you take 20 2/5 and divide it by 2/5, you should be left with the number of sheets of sheetrock there are in the stack. To divide it, you my have to convert the fraction to a decimal, just FYI. Considering this is marked as a college-level question, I assume you already know how to do this. Hope this helps ya, pal.

Answer:
The population be after 15 years is 171376.
Step-by-step explanation:
Given : A population of 110,000 grows 3% per years 15 years.
To find : How much will the population be after 15 years?
Solution :
Exponential growth population model is given by,
![P(t)=P_o(1+r)^t](https://tex.z-dn.net/?f=P%28t%29%3DP_o%281%2Br%29%5Et)
Where,
P(t) is the population at time (t)
is the initial value of the population
r=3%=0.03 is the annual rate of growth
t=15 is the time in years.
Substitute the value,
![P(t)=110000(1+0.03)^{15}](https://tex.z-dn.net/?f=P%28t%29%3D110000%281%2B0.03%29%5E%7B15%7D)
![P(t)=110000(1.03)^{15}](https://tex.z-dn.net/?f=P%28t%29%3D110000%281.03%29%5E%7B15%7D)
![P(t)=110000\times 1.5579](https://tex.z-dn.net/?f=P%28t%29%3D110000%5Ctimes%201.5579)
![P(t)=171376.41](https://tex.z-dn.net/?f=P%28t%29%3D171376.41)
Therefore, the population be after 15 years is 171376.
