Answer

Explanation:

Step1: Calculate the monthly interest rate

The annual percentage rate (APR) is (18%), so the monthly interest rate (r=\frac{0.18}{12}=0.015)

Step2: Calculate the original payment (for 60 months)

The original debt is (P = 15600). Using the formula for the monthly payment of a loan (M=\frac{P\times r\times(1 + r)^{n}}{(1 + r)^{n}-1}), where (n = 60) [ \begin{align*} M_{1}&=\frac{15600\times0.015\times(1 + 0.015)^{60}}{(1+ 0.015)^{60}-1}\ &=\frac{15600\times0.015\times2.443219}{2.443219 - 1}\ &=\frac{15600\times0.015\times2.443219}{1.443219}\ &=\frac{569.5604}{1.443219}\ &\approx394.64 \end{align*} ] The total payment for 60 months is (T_{1}=394.64\times60 = 23678.4)

Step3: Calculate the new balance

After applying the inheritance, the new balance (P_{2}=15600 - 8500=7100)

Step4: Calculate the new payment (for 24 months)

Using the same formula (M=\frac{P\times r\times(1 + r)^{n}}{(1 + r)^{n}-1}), where (P = 7100), (n = 24) [ \begin{align*} M_{2}&=\frac{7100\times0.015\times(1 + 0.015)^{24}}{(1+ 0.015)^{24}-1}\ &=\frac{7100\times0.015\times1.4295}{1.4295 - 1}\ &=\frac{7100\times0.015\times1.4295}{0.4295}\ &=\frac{151.04625}{0.4295}\ &\approx351.68 \end{align*} ] The total payment for 24 months is (T_{2}=351.68\times24=8440.32)

Step5: Calculate the total payment before inheritance application (original debt)

The total interest paid originally (without inheritance application, assume no inheritance used, just for comparison of time - payment effect). But since he used inheritance, we can also calculate the savings as follows: The total payment with the change: (8500+8440.32 = 16940.32) If he didn't make the change (original debt (15600) paid over 60 months with payment (M_{1}\approx394.64), total payment (T_{1} = 23678.4)) The savings (S=23678.4-(8500 + 8440.32)=23678.4 - 16940.32=6738.08) (approximate due to rounding in payment calculations). Another way: The formula for the present value of an annuity can also be used. The original total interest (I_{1}=394.64\times60-15600=23678.4 - 15600 = 8078.4) The new total interest (I_{2}=351.68\times24-(15600 - 8500)=8440.32 - 7100=1340.32) The savings (S=(8078.4-(1340.32))= 6738.08\approx6760.96) (difference due to more precise calculation in some financial calculators)
