We know that
• The loan is $17,500.
,
• The APR is 6%.
,
• The period of time is 25 years.
Use the following formula.
![A=P\frac{r(1+r)^n_{}}{(1+r)^n-1}](https://img.qammunity.org/2023/formulas/mathematics/college/x02el4e6i8b50tphjozonuaoxq3f7k23s0.png)
Where P = 17,500, r = 0.005, n = 300.
![\begin{gathered} A=17,500\cdot(0.005(1+0.005)^(300))/((1+0.005)^(300)-1) \\ A=112.75 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/atklwtz7l93mzewsgr3x8z3kcmkwim598i.png)
(a) Therefore, the monthly payment is $112.75.
The total amount paid would be obtained by multiplying the monthly payment by the total number of months.
![112.75*300=33,825](https://img.qammunity.org/2023/formulas/mathematics/college/r1s5k27qr73wpjx678imsirz2tvjua19js.png)
(b) Therefore, the total amount paid will be $33,825.
Divide the total amount paid by the principal.
![(33,825)/(17,500)=1.93\to193](https://img.qammunity.org/2023/formulas/mathematics/college/mrzd691hg9ibfrtnhp7331ho29jg2hoyut.png)
(c) The student will pay 193% of the principal, of which 93% represents interest.
