Answer:
The answer to your problem is, D. $13,564.80
Explanation:
We know it took her 4 years to pay this amount. Let's solve for the total amount she paid including the interest.
12,560 x 0.02 = 251.2 per year
251.2 x 4 = 1004.8 dollars for 4 years.
1004.8 + 12,560 = 13,564.8 dollars.
Thus the answer to your problem is, D. $13,564.80
