For the answer to the question above asking what was the amount of the withdraw if <span>Doris put $4000 in a 2-year cd paying 6% interest, compounding monthly. after 2 years, she withdrew all her money?</span>
First year Interest: I(1) = 4000[(1.005)^12 - 1] = 246.71 = penalty for early withdrawal
Value after two years: P(2) = 4000(1.005)^24 = 4508.64
Value after 2 years with penalty: V = 4000(1.005^24 - 1.005^12 + 1) = $4261.93
The amplitude is 4 I believe
