<u>The formula for the monthly payment</u>.....
, where P = the principal amount, r = the monthly interest rate and n = the total number of months.
Here annual interest rate is given as 4.5%
So, the monthly interest rate 
Total number of months 
Also given that, the principal amount is $225000
a. So, the monthly payment will be.....
![M= \frac{P(1+r)^nr}{[(1+r)^n] -1}\\ \\ M= \frac{225000(1+0.00375)^3^6^0*0.00375}{(1+0.00375)^3^6^0 -1}\\ \\ M= \frac{225000(1.00375)^3^6^0*0.00375}{(1.00375)^3^6^0 -1} \\ \\ M \approx 1140](https://tex.z-dn.net/?f=M%3D%20%5Cfrac%7BP%281%2Br%29%5Enr%7D%7B%5B%281%2Br%29%5En%5D%20-1%7D%5C%5C%20%5C%5C%20M%3D%20%5Cfrac%7B225000%281%2B0.00375%29%5E3%5E6%5E0%2A0.00375%7D%7B%281%2B0.00375%29%5E3%5E6%5E0%20-1%7D%5C%5C%20%5C%5C%20M%3D%20%5Cfrac%7B225000%281.00375%29%5E3%5E6%5E0%2A0.00375%7D%7B%281.00375%29%5E3%5E6%5E0%20-1%7D%20%5C%5C%20%5C%5C%20M%20%5Capprox%201140)
Thus, the monthly payment will be approximately $1140
b. The <u>total amount paid</u> over the term of the loan will be:
c. As the principal amount was $225000 , so the amount of interest 
So, the percentage of amount that is paid toward the principal 
and the percentage of amount that is paid toward the interest
