Sagot :

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.

What is the formula for compound interest?

[tex]Amount=p(1+\frac{r}{n} )^{nt}[/tex]

p = 8575

r = 7.1% or 0.071

n = 12

t = 4

Putting the values in formula we get

[tex]Amount=8575(1+\frac{0.071}{12} )^{12(4)}[/tex]

[tex]Amount=8575(1+\frac{0.071}{12} )^{48}[/tex]

Solving this we get;

Amount = $11381.94

For the next part we have EMI formula as,

[tex]EMI=\frac{pr(1+r)^{n} }{(1+r)^{n-1}}[/tex]

p = 11381.94

[tex]r=\frac{7.1}{\frac{12}{100} }=0.005917[/tex]

[tex]n=(12)(10)\\n=120[/tex]

[tex]EMI=\frac{11381.94(0.005979)(1+0.005979)^{120} }{(1+0.005979)^{120}-1}[/tex]

EMI = $132.74

Now total payments made in 120 months (10 years) =

[tex]132.74(120)=15928.80[/tex]  dollars

interest paid =

[tex]15928.80-8575=7353.80[/tex] dollars

Hence, Roderigo will pay $7353.80
