Determine amount of investment if $400 is invested at a annual interest rate of 7.25% for 7 Years round to nearest penny. I'm going to post my formula someone correct me if wrong please?

Respuesta :

A=p(1+i)^n
A=400(1+0.0725)^7=652.89

Answer:

The answer is $682.80

Step-by-step explanation:

P = $400

rate = 7.25 or 0.0725

time = 7 years

n = 1

Compound interest formula is : [tex]P(1+\frac{r}{n})^{nt}[/tex]

Here n = 1

So, we will simply take [tex]P(1+r)^{t}[/tex]

Putting values in the formula we get,

[tex]400(1+0.0725)^{7}[/tex]

400(1.632) = $652.80
