For the answer to the question above asking what was the amount of the withdraw if Doris put $4000 in a 2-year cd paying 6% interest, compounding monthly. after 2 years, she withdrew all her money?

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
