Using it's formula, it is found that the monthly payments for the loan of the apartment is of $7,260.50.
<h3>What is the monthly payment formula?</h3>
It is given by:
![A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}](https://tex.z-dn.net/?f=A%20%3D%20P%5Cfrac%7B%5Cfrac%7Br%7D%7B12%7D%5Cleft%281%20%2B%20%5Cfrac%7Br%7D%7B12%7D%5Cright%29%5En%7D%7B%5Cleft%281%20%2B%20%5Cfrac%7Br%7D%7B12%7D%5Cright%29%5En%20-%201%7D)
In which:
- n is the number of payments.
In this problem, the parameters are given as follows:
P = 500000, r = 0.123, n = 12 x 10 = 120.
Hence:
r/12 = 0.123/12 = 0.01025.
Then, the monthly payments will be of:
![A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}](https://tex.z-dn.net/?f=A%20%3D%20P%5Cfrac%7B%5Cfrac%7Br%7D%7B12%7D%5Cleft%281%20%2B%20%5Cfrac%7Br%7D%7B12%7D%5Cright%29%5En%7D%7B%5Cleft%281%20%2B%20%5Cfrac%7Br%7D%7B12%7D%5Cright%29%5En%20-%201%7D)
![A = 500000\frac{0.01025(1+0.01025)^{120}}{(1+0.01025)^{120} - 1}](https://tex.z-dn.net/?f=A%20%3D%20500000%5Cfrac%7B0.01025%281%2B0.01025%29%5E%7B120%7D%7D%7B%281%2B0.01025%29%5E%7B120%7D%20-%201%7D)
A = 7260.50.
