Answer:
a: 247.43 interest
b: 15,039.31 dirty price of the purchase
Step-by-step explanation:
We purchase the note at the quoted price plus the accrued interest at the time:
accrued interest:
principal x rate x time
we express time as a portion of year.
14,000 x 4.388% x 145/360 = $ 247.4344
note market price:
14,000 x 105.65625/100 = 14,791.875
dirty price:
principal + interest
14,791.875 + 247.4344 = 15,039.31
