The answer to your question is 34.13%
The interest rate is 3.5%.
EXPLANATION
We substitute the given values into the formula;
![A=P(1+\frac{r}{100})^t](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7B100%7D%29%5Et)
to obtain
![6427.35=6000(1+\frac{r}{100})^2](https://tex.z-dn.net/?f=6427.35%3D6000%281%2B%5Cfrac%7Br%7D%7B100%7D%29%5E2)
We divide through by 6000 to obtain,
![\frac{6427.35}{6000}=(1+\frac{r}{100})^2](https://tex.z-dn.net/?f=%5Cfrac%7B6427.35%7D%7B6000%7D%3D%281%2B%5Cfrac%7Br%7D%7B100%7D%29%5E2)
This implies that,
![1.071225=(1+\frac{r}{100})^2](https://tex.z-dn.net/?f=1.071225%3D%281%2B%5Cfrac%7Br%7D%7B100%7D%29%5E2)
We take the square root of both sides,
![\sqrt{1.071225}=(1+\frac{r}{100})](https://tex.z-dn.net/?f=%5Csqrt%7B1.071225%7D%3D%281%2B%5Cfrac%7Br%7D%7B100%7D%29)
This gives us,
![1.035=(1+\frac{r}{100})](https://tex.z-dn.net/?f=1.035%3D%281%2B%5Cfrac%7Br%7D%7B100%7D%29)
Add -1 to both sides of the equation to obtain
![0.035=\frac{r}{100}](https://tex.z-dn.net/?f=0.035%3D%5Cfrac%7Br%7D%7B100%7D)
Multiply through by 100 to obtain;
![r=3.5](https://tex.z-dn.net/?f=r%3D3.5)

Answer:
Step-by-step explanation:
For every 10 assignments you get 1 homework pass. So you would multiply them by two and up more.
So here's some of your answers:
10:1
20:2
30:3
40:4
50:5
60:6
70:7
80:8
90:9
100:10
You would just continue this pattern.
