Determine the compound interest
This is calculated using:
![I = P(1 + \frac{r}{n})^{nt} - P](https://tex.z-dn.net/?f=I%20%3D%20P%281%20%2B%20%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D%20-%20P)
![I = 200(1 + \frac{9\%}{1})^{1*5} - 200](https://tex.z-dn.net/?f=I%20%3D%20200%281%20%2B%20%5Cfrac%7B9%5C%25%7D%7B1%7D%29%5E%7B1%2A5%7D%20-%20200)
![I = 200(1 + \frac{0.09}{1})^5 - 200](https://tex.z-dn.net/?f=I%20%3D%20200%281%20%2B%20%5Cfrac%7B0.09%7D%7B1%7D%29%5E5%20-%20200)
![I = 200(1 + 0.09)^5 - 200](https://tex.z-dn.net/?f=I%20%3D%20200%281%20%2B%200.09%29%5E5%20-%20200)
![I = 200(1.09)^5 - 200](https://tex.z-dn.net/?f=I%20%3D%20200%281.09%29%5E5%20-%20200)
![I = 307.72 - 200](https://tex.z-dn.net/?f=I%20%3D%20307.72%20-%20200)
![I = 107.72](https://tex.z-dn.net/?f=I%20%3D%20107.72)
<em>Hence, the total interest earned is £107.72</em>
Answer:
C. x > 35
Step-by-step explanation:
X+11>46
X>46
-11
X>35
Average is the total of x divide by number of x.
Here, we have,
x = 55, 64, 60, 61
number of x = 4
Total of x = 55 + 64 + 60 + 61 = 240
So, the average is,
240 / 4 = 60
