P = 5000 = principal
r = 0.08 = decimal form of the annual interest rate
n = 2 = number of times we compound the money per year
t = 3 years
Use those values to find the following:
A = P*(1+r/n)^(n*t)
A = 5000*(1+0.08/2)^(2*3)
A = 6326.59509248
A = 6326.60
This is how much is in the account at the 3 year mark.
Subtract off the principal to get the interest made
i = A - P
i = 6326.60 - 5000
i = 1326.60
