i = .045/12 = .00375
n = 48
first we have to find the payment
Present Value= payment[1 - (1+i)^-n]/i
30000=paym[1 - (1.00375)^-48]/.00375
.
.
paym = 684.10
Now find the Amount of 36 of those payments
Amount = 684.10[(1.00375)^36 - 1]/.00375
= 26314.83
Find out how much the debt would be worth after 3 years had no payments been made
Value of debt = 30000(1.00375)^36
=34327.44
Finally subtract those two values
34329.44-26314.83
=8012.61
