Total = principal * (1 + rate)^years
Total = 3,400 * (1.022)^.25

So, after 3 months, $18.55 in interest is earned.
I believe the next one would be 13.2 because if you add 8.4 to -6.4 it gets 4.8 so you just do the same thing

Answer:
The division was computed incorrectly.
Step-by-step explanation:
Given
Workings:
to percentage
![\frac{8}{5} = 1.6 = 160\%](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B5%7D%20%3D%201.6%20%3D%20160%5C%25)
Required
Explain his error
The question says 5/8
Instead, Alejandro's working shows 8/5.
This working is done in an incorrect order and the correct solution is:
Let
![x = \frac{5}{8}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B5%7D%7B8%7D)
Solve the fraction
![x = 0.625](https://tex.z-dn.net/?f=x%20%3D%200.625)
Multiply by 100%
![x = 0.625 * 100\%](https://tex.z-dn.net/?f=x%20%3D%200.625%20%2A%20100%5C%25)
![x = 62.5\%](https://tex.z-dn.net/?f=x%20%3D%2062.5%5C%25)
<em>Hence, option (a) is correct.</em>
The area of the entire circle is pi*(7)^2, or 49pi.
Due to the 90 degree angle, the area of the larger blue sector is
90
------- * 49 pi = 49/4 units^2
360
The area of the smaller blue sector is
48
------- 49 pi = (2/15)(49 pi) = 98 pi/15 units^2
360
The total area of the blue sectors is the sum of 98 pi/15 and 49 pi/4 (units^2):
59 units^2
