Respuesta :

Answer:

[tex]I=\$77,813.68[/tex]

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]t=25\ years\\ P=\$30,000\\ r=5.25\%=5.25/100=0.0525\\n=1[/tex]  

substitute in the formula above

[tex]A=30,000(1+\frac{0.0525}{1})^{25*1}[/tex]  

[tex]A=30,000(1.0525)^{25}[/tex]  

[tex]A=\$107,813.68[/tex]  

Find out the total interest I

[tex]I=A-P[/tex]

so

[tex]I=\$107,813.68-\$30,000=\$77,813.68[/tex]

$77,813.68
