Anna will need ____ to deposit $.

Respuesta :

Answer:

Anna will need to deposit [tex]\$9,050.25[/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=2\ years\\A=\$10,000\\ r=0.05\\n=12[/tex]  

substitute in the formula above  and solve for P

[tex]10,000=P(1+\frac{0.05}{12})^{12*2}[/tex]  

[tex]10,000=P(1.0042)^{24}[/tex]  

[tex]P=10,000/(1.0042)^{24}[/tex]    

[tex]P=\$9,050.25[/tex]
