Answer:
Percentage of finance charge as service charge= 15.6%
Explanation:
Monthly installment = Loan amount /annuity factor
Annuity factor = (1- (1+r)^(-n))/r
r - semi-annul interest rate = 9.58%/2
n= number of period : 2×8 = 16
Annuity factor =( 1- (1.0479))^(-16)/0.0479
=11.0016
Monthly installment = 15,360 /11.00
=$1396.160
TotaL amount paid = 1396.160459× 16 =22,338.56
Interest charges = 22,338.56 - 15,360
= $6978.56
Percentage of total finance charge as service charge=
=1294.64/(1294.64+6978.567348)× 100
= 15.6%
