Answer:

Explanation:
Mrs. Siebenaller bought a bus for 25,000 with a 7% interest rate and she gets a loan payoff of 60 months,
We know that,
![\text{PV of annuity}=P\left[(1-(1+r)^(-n))/(r)\right]](https://img.qammunity.org/2019/formulas/business/high-school/zcse4794vfy1xax0rqcm9afqw3lklci9bi.png)
Where,
PV = Present value of annuity = 25000,
r = rate of interest of each period =
% monthly
n = number of periods = 60 months,
Putting the values,
![\Rightarrow 25000=P\left[(1-(1+(0.07)/(12))^(-60))/((0.07)/(12))\right]](https://img.qammunity.org/2019/formulas/mathematics/high-school/9al7oha5p7guc8ltw1gsuf0kyqsiopat6b.png)
![\Rightarrow P=(25000)/(\left[(1-(1+(0.07)/(12))^(-60))/((0.07)/(12))\right])](https://img.qammunity.org/2019/formulas/mathematics/high-school/g0nwgchkyxicolgc3ekrc6dn0otpf9ptu4.png)

Hence total amount paid is,

Therefore interest amount is,
