Answer:
$3,255.65
Explanation:
I assume that you would like to calculate the result of $2,500 sitting for 6 years at an interest rate of 4.5%. You are going to want to use the compound interest formula, which is shown below.

P = initial balance 
r = interest rate 
n = number of times compounded annually 
t = time
Now lets plug in the values into the equation.
 = 3,255.65
 = 3,255.65
Your answer is $3,255.65
