Recall
A = P (1+i/n)nt and A - P = interest earned
A = accumulated or future value
P = principal = $500,000
i = rate = 8.6%
t = time = 5 years
n = compounding period = 4 = quarterly
A = (500000) (1+0.086/4)4•5
A = (500000) (1.53) = 765,134 rounded to whole dollars
Compound Interest earned = 765134 - 500000 = $265,134
