ID: 3145082 • Letter: C
Question
Explanation / Answer
(a)
Using the formula :
P = r(PV)/ [ 1-(1+r)-n]
r= 0.09/12 =0.0075
PV= $7500
n = 4×12= 48
P = [0.0075×7500]/[1-(1+0.0075)-48]
= $186.64
(b) Total amount paid over the course of loan :
A = $186.64×12×4= $8958.72
(c) of the total amount paid, the percentage that paid towards the principle is :
(7500/8958.72)×100= 83.71%
Interest = 8958.72-7500 = $1458.72
Of the total amount paid, the percentage that paid toward the interest is :
(1458.72/8958.72)×100 = 16.29%
