-- Time
-- compounded once in a year
Required
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:
1 is greater than -5

1 is greater than -5 because 1 is a whole number while -5 is a number that isn't positive causing it to automatically be lower then 1.
On average she read 6 books per month because 6+4+8=18 then you divide 18 by 3 which equals out to 6
Answer:
Polynomial Function: 3.5n + 1
Total Price of the Apples: $32.50
Step-by-step explanation:
The polynomial function is 3.5n + 1:
The 3.5n comes from the $3.50 it costs to buy an apple, and the n comes from the amount of apples bought. The 1 then comes from the tax that is added onto the price.
The total price of the apples:
3.5n + 1 ; n = 3^3 = 9
(3.5 x 9) + 1
31.5 + 1
32.5
$32.50
