Roderigo will pay $7353.80 in interest.
Interest capitalization means the interest earned is added to the principle amount so first we will use compound interest formula.
<h3>
What is the formula for compound interest?</h3>
![Amount=p(1+\frac{r}{n} )^{nt}](https://tex.z-dn.net/?f=Amount%3Dp%281%2B%5Cfrac%7Br%7D%7Bn%7D%20%29%5E%7Bnt%7D)
p = 8575
r = 7.1% or 0.071
n = 12
t = 4
Putting the values in formula we get
![Amount=8575(1+\frac{0.071}{12} )^{12(4)}](https://tex.z-dn.net/?f=Amount%3D8575%281%2B%5Cfrac%7B0.071%7D%7B12%7D%20%29%5E%7B12%284%29%7D)
![Amount=8575(1+\frac{0.071}{12} )^{48}](https://tex.z-dn.net/?f=Amount%3D8575%281%2B%5Cfrac%7B0.071%7D%7B12%7D%20%29%5E%7B48%7D)
Solving this we get;
Amount = $11381.94
For the next part we have EMI formula as,
![EMI=\frac{pr(1+r)^{n} }{(1+r)^{n-1}}](https://tex.z-dn.net/?f=EMI%3D%5Cfrac%7Bpr%281%2Br%29%5E%7Bn%7D%20%7D%7B%281%2Br%29%5E%7Bn-1%7D%7D)
p = 11381.94
![r=\frac{7.1}{\frac{12}{100} }=0.005917](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B7.1%7D%7B%5Cfrac%7B12%7D%7B100%7D%20%7D%3D0.005917)
![n=(12)(10)\\n=120](https://tex.z-dn.net/?f=n%3D%2812%29%2810%29%5C%5Cn%3D120)
![EMI=\frac{11381.94(0.005979)(1+0.005979)^{120} }{(1+0.005979)^{120}-1}](https://tex.z-dn.net/?f=EMI%3D%5Cfrac%7B11381.94%280.005979%29%281%2B0.005979%29%5E%7B120%7D%20%7D%7B%281%2B0.005979%29%5E%7B120%7D-1%7D)
EMI = $132.74
Now total payments made in 120 months (10 years) =
dollars
interest paid =
dollars
Hence, Roderigo will pay $7353.80

C is irrational because there is no definite square root for 15 whereas the square root of 36=6
Answer:
x=150
y=240
Step-by-step explanation:
*Use simultaneous equation solving
1.Label your equations
x+y=390......1
2x+4y=1260......2
*make one of the unknowns subject of formula, to form equation 2
x=390-y.....3
*sub.3 into 2
2(390-y)+4y=1260
780-2y+4y=1260
2y+780=1260
y=240
sub. y into 3
x=390-y
x=390-240
x=150
