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?
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 : \(P(1+\frac{r}{n})^{nt}\)
Here n = 1
So, we will simply take \(P(1+r)^{t}\)
Putting values in the formula we get,
\(400(1+0.0725)^{7}\)
400(1.632) = $652.80
