Answer:

[tex]\$7,878.21[/tex]  

Step-by-step explanation:

The question is

What is the amount of money to be invested now?

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=\$19,000\\ r=9\%=9/100=0.09\\n=2[/tex]  

substitute in the formula above

[tex]19,000=P(1+\frac{0.09}{2})^{2*10}[/tex]  

solve for P

[tex]19,000=P(1.045)^{20}[/tex]  

[tex]P=19,000/(1.045)^{20}[/tex]  

[tex]P=\$7,878.21[/tex]
