Doreen Short was looking over the repayment schedule for a loan of $40,000, the final payment and amount saved for the options are mathematically given as
Generally, the equation for the interest is mathematically given as
I= balance*percentage/12
Therefore
I=17,565. 74*0.09/12
I=131.7
The final payment
F=I+B
F=131.7+17,565. 74
F=17697.5
Amount saved
AS=19*995.40 -17697.5
AS=1215.12
b) For the loan is paid off with payment 36 with a loan balance of $12,285. 66
I= balance*percentage/12
Therefore
I= 12,285. 66*0.09/12I92.142
I=92.142
Final payment
F=I+B
F=92.142+12377.80
F=12377.80
Amount saved
AS=13*995.40-12377.80
AS=$562.40
c) For the loan is paid off with payment 48 with a previous balance of $988. 9
I= balance*percentage/12
I= 988.09*0.09/12
I=7.41
Therefore
F=7.41* +988.09
F=$995.40
The Amount saved is zero
