You can put this solution on YOUR website!
Let +n+ = the number of years to pay back the loan
+405.18+%2F+n+ = 1 years interest
--------------
+.045%2A2251+=+405.18+%2F+n+
+101.295+=+405.18+%2F+n+
+n%2A101.295+=+405.18+
+n+=+405.18+%2F+101.295+
+n+=+4+
Sallie Mae is giving her 4 years to repay the loan with interest
