Answer

# Explanation: ## Step1: Calculate the interest rate for 18 - months The annual interest rate $r = 8\%=0.08$. For 18 months ($t = 1.5$ years), the simple - interest formula is $I = Prt$. ## Step2: Calculate the penalty for the early withdrawal The amount withdrawn $P = 6000$. Using the simple - interest formula $I=Prt$, we substitute $P = 6000$, $r = 0.08$, and $t = 1.5$. So $I=6000\times0.08\times1.5=720$. ## Step3: Calculate the interest that the $6000$ would have earned from the 4th year to the 12th year (9 years) Using the simple - interest formula $I = Prt$ again, with $P = 6000$, $r = 0.08$, and $t = 9$. So $I=6000\times0.08\times9 = 4320$. ## Step4: Calculate the total loss of interest The total loss of interest is the sum of the penalty and the interest that the withdrawn amount would have earned in the remaining years of the CD. The total loss $L=720 + 4320=5040$. # Answer: D. $5,040$
