Answer:
A) There was no cash paid in 2016 (that means $0), rather both the interest and principal were paid on March 31, 2017.
B) [(Amount x rate) / 12] x 3 months
=[(90,000 x 8%) / 12] x 3 months
= (7,200 / 12) x 3
= 600 x 3
= $1,800
C) 90,000 + 1,800 = $91,800
D) (600 x 6 months) + 90,000
= 3,600 + 90,000
= $93,600
E) 600 x 3 months
= $1,800.
