How much money must be deposited now in an
account paying 7.25% annual interest, compounded
quarterly, to have a balance of $1000 after 10
years?

Respuesta :

Answer:

[tex]\$487.48[/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=\$1,000\\ r=7.25\%=7.25/100=0.0725\\n=4[/tex]  

substitute in the formula above

[tex]1,000=P(1+\frac{0.0725}{4})^{4*10}[/tex]  

[tex]1,000=P(\frac{4.0725}{4})^{40}[/tex]

[tex]P=1,000/(\frac{4.0725}{4})^{40}[/tex]

[tex]P=\$487.48[/tex]
