Answer: $50.81
Explanation:
Simple interest = principal x rate x time
The principal was $1,400
The rate is 6.40% (0.064)
The chart indicates that it is 207 days from April 15 to Nov 8
Therefore the amount of time is (207/365).
Simple interest = principal x rate x time
Simple interest= $1,400 x 0.064 x (207/365)
Simple interest= $50.81
Therefore the penalty is $50.81
