An investment of $2000.00 is earning interest at the rate of 6.2% compounded quarterly over 5 years. Approximately how much interest is earned on the investment?

$720.37

Step-by-step explanation:

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:

To find the interest earned, just subtract the principal of 2,000 from 2,720.37:

The interest earned is $720.37
