Answer:
a) annual payment = PV of the loan / PV annuity factor
i = 14%
n = 3
PV annuity factor, 14%, 3 periods = 2.3216
annual distribution = $15,000 / 2.3216 = $6,461.06
b)
principal cash payment interest paid principal paid ending bal.
15,000 6,461.06 2,100 4,361.06 10,638.94
10,638.94 6,461.06 1,489.45 4,971.61 5,667.33
5,667.33 6,461.06 793.73 5,667.33 0
c) the interest portion declines with every payment because interest is charged over the principal's balance, and if the principal decreases, then the interest will be lower.
