Formula for compounded interest: A = P(1 + (r/n)^(nt)
A = final amount, p = starting amount, r = interest rate, n = number of times interest is applied per time frame, and t = number of times period elapsed.
P = 4000 , r = .036 , t = 5 , and n = 12
A = 4000( 1 + (.036/12)(12 x 5)
A = 4000( 1 + .003) ^ (60)
A = 4000 ( 1.003) ^(60)
A = $ 4787.58
