Step-by-step explanation:
Please consider the complete question.
A city has a population of 390,000 people. Suppose that each year the population grows by 6.75%. What will the population be after 13 years? Round your answer the nearest whole number.
We will use exponential growth formula to solve our given problem.
, where,
y = Final value,
a = Initial value,
r = Growth rate in decimal form,
![6.75\%=\frac{6.75}{100}=0.0675](https://tex.z-dn.net/?f=6.75%5C%25%3D%5Cfrac%7B6.75%7D%7B100%7D%3D0.0675)
![y=390,000\cdot (1+0.0675)^x](https://tex.z-dn.net/?f=y%3D390%2C000%5Ccdot%20%281%2B0.0675%29%5Ex)
![y=390,000\cdot (1.0675)^x](https://tex.z-dn.net/?f=y%3D390%2C000%5Ccdot%20%281.0675%29%5Ex)
To find the population after 13 years, we will substitute
in population growth equation as:
![y=390,000\cdot (1.0675)^{13}](https://tex.z-dn.net/?f=y%3D390%2C000%5Ccdot%20%281.0675%29%5E%7B13%7D)
![y=390,000\cdot 2.3376661492982871](https://tex.z-dn.net/?f=y%3D390%2C000%5Ccdot%202.3376661492982871)
![y=911689.798226331969](https://tex.z-dn.net/?f=y%3D911689.798226331969)
Upon rounding to nearest whole number, we will get:
![y\approx 911,690](https://tex.z-dn.net/?f=y%5Capprox%20911%2C690)
Therefore, the population of the city after 13 years would be 911,690.
