calculate the future value of an investment of $8,500 if it is to be invested for 9 years at an interest rate of 6.1%, compounded quarterly.

i = .061/4 = .01525

n= 9(4) = 36

amt = 8500(1.01525)^36 = ....

To calculate the future value of an investment compounded quarterly, you can use the formula for compound interest:

Future Value = Principal * (1 + (interest rate / n))^(n * time)

Where:
- Principal is the initial investment amount ($8,500)
- Interest rate is the annual interest rate (6.1% or 0.061)
- n is the number of times interest is compounded per year (quarterly, so n = 4)
- Time is the length of the investment in years (9 years)

Let's plug in the values into the formula:

Future Value = $8,500 * (1 + (0.061 / 4))^(4 * 9)

Now, let's calculate it step by step:

First, calculate the value inside the parentheses:

1 + (0.061 / 4) = 1.01525

Next, raise this value to the power of (4 * 9):

(1.01525)^(4 * 9) = 1.01525^36 ≈ 1.65672228

Finally, multiply the result by the principal:

$8,500 * 1.65672228 ≈ $14,070.15

Therefore, the future value of an investment of $8,500, compounded quarterly at an interest rate of 6.1% over 9 years, would be approximately $14,070.15.
