Determine the amount of money that should be invested at a rate of 8% compounded quarterly to produce a final balance of $20000 after 10 years

Respuesta :

Answer:

[tex]\$9,057.81[/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=10\ years\\ A=\$20,000\\ r=8\%=8/100=0.08\\n=4[/tex]  

substitute in the formula above

[tex]20,000=P(1+\frac{0.08}{4})^{4*10}[/tex]  

Solve for P

[tex]20,000=P(1.02)^{40}[/tex]  

[tex]P=20,000/(1.02)^{40}[/tex]  

[tex]P=\$9,057.81[/tex]
