The answer is 31,500.
Let's clarify some things :
1% of 45,000 is 450
Maybe you're wondering why , it's actually very simple .
Just move the decimal to the left once if you want to find 10% , move the decimal twice if you want to find 1%.
We now that 1% equals 450. Then 2% equals to....
Well just add another 1% .
450 + 450 or 450 times 2
Which equals 900.
Now we want to find what's the population after 15 years.
900 times 15= 13,500
But that's not the answer ....
That's what is decreasing.
45,000 - 13,500= 31,500
That's why the answer is 31,500.
The given equation is ![2c^2=16c-32](https://tex.z-dn.net/?f=2c%5E2%3D16c-32)
We need to determine the type of solution and the number of solutions.
<u>Solving the equation:</u>
Let us solve the equation to determine the number of solution and the type of solution.
Subtracting both sides of the equation by 16c, we get;
![2c^2-16c=-32](https://tex.z-dn.net/?f=2c%5E2-16c%3D-32)
Adding both sides of the equation by 32, we have;
![2 c^{2}-16 c+32=0](https://tex.z-dn.net/?f=2%20c%5E%7B2%7D-16%20c%2B32%3D0)
Let us solve the equation using the quadratic formula.
Thus, we have;
![c=\frac{-(-16) \pm \sqrt{(-16)^{2}-4 \cdot 2 \cdot 32}}{2 \cdot 2}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B-%28-16%29%20%5Cpm%20%5Csqrt%7B%28-16%29%5E%7B2%7D-4%20%5Ccdot%202%20%5Ccdot%2032%7D%7D%7B2%20%5Ccdot%202%7D)
Simplifying, we get;
![c=\frac{16 \pm \sqrt{{256}-256}}{4}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B16%20%5Cpm%20%5Csqrt%7B%7B256%7D-256%7D%7D%7B4%7D)
![c=\frac{16 \pm \sqrt{0}}{4}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B16%20%5Cpm%20%5Csqrt%7B0%7D%7D%7B4%7D)
![c=\frac{16}{4}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B16%7D%7B4%7D)
![c=4](https://tex.z-dn.net/?f=c%3D4)
Thus, the solution of the equation is 4.
Hence, the equation has one rational solution.
Therefore, Option A is the correct answer.
