If $650 is invested in a bank account that earns a nominal 2.5% yearly interest, compounded quarterly, then how much is the investment worth after 10 years

Respuesta :

Answer:

[tex]\$833.97[/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\\ P=\$650\\ r=2.5\%=2.5/100=0.025\\n=4[/tex]  

substitute in the formula above

[tex]A=650(1+\frac{0.025}{4})^{4*10}[/tex]  

[tex]A=650(1.00625)^{40}[/tex]  

[tex]A=\$833.97[/tex]
