Answer:
C, the three lengths of a triangular sail are 12 feet, 16 feet and 20 feet
Step-by-step explanation:
Just did the test
If the shorter leg is 12 the only answer larger than 12 is 16.
Using the monthly payment formula, it is found that:
- Her monthly payments are of $105.46.
- The total finance charge is of $3,111.04.
<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.
Considering that she must pay 20% down, the parameters are given by:
P = 0.8 x 2900 = 2320, r/12 = 0.085/12 = 0.007083, n = 24.
Hence the monthly payments are found as follows:
![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 = 2320\frac{0.007083(1.007083)^{24}}{(1.007083)^{24} - 1}](https://tex.z-dn.net/?f=A%20%3D%202320%5Cfrac%7B0.007083%281.007083%29%5E%7B24%7D%7D%7B%281.007083%29%5E%7B24%7D%20-%201%7D)
A = $105.46.
The total finance charge is composed by the <u>down payment plus the 24 monthly payments</u>, hence:
F = 0.2 x 2900 + 24 x 105.46 = $3,111.04.
