Respuesta :
I have another total loan payment formula (see attached):
Total = rate * principal * # of payments / (1-((1 + rate)^-n))
Total = .005 * 15,000 * 60 / (1- ((1.005)^-60)
Total = 4,500 / (1 -0.7413721962)
Total = 4,500 / 0.2586278038
Total = 17,399.52
I know that is NOT one of the answers but I am sure of the formula and the calculations. I hope this helps.

Answer: $20,073.50
Step-by-step explanation:
Given : Principal amount : [tex]P=\$15,000[/tex]
Interest rate per year: [tex]i=6\%=0.06[/tex]
Time period : [tex]t=5[/tex]
The formula to calculate the compound amount after t years is given by :-
[tex]A=P(1+i)^t[/tex]
Then , the amount she have paid at the end of the five-year loan term is given by :-
[tex]A=15000(1+0.06)^5=20073.383664\approx20073.50[/tex]
Hence, the amount she have paid at the end of the five-year loan term = $20,073.50
