Let the loan amount at 7% be $x.Therefore,the amount of loan at 15% is $14000-x

By the problem,

0.07x+0,15(14000-x)=15000-14000=1000

or,0.07x+2100-0.15x=1000

or,-0.08x=1000-2100= -1100

or x= -1100/-0.08

=13,750

Therefore,the loan at 7% was $13,750

This question is impossible unless the question specifies how long after the loan was taken out did the student pay it back.
