You can put this solution on YOUR website!
Let +x+ = pounds of chicken
salad he bought
+14+-+x+ = pounds of tuna
salad he bought
--------------------------
+9x+%2B+6%2A%28+14+-+x+%29+=+111+
+9x+%2B+84+-+6x+=+111+
+3x+=+27+
+x+=+9+
The answer is:
(D) 9 pounds
--------------
check:
+9x+%2B+6%2A%28+14+-+x+%29+=+111+
+9%2A9+%2B+6%2A5+=+111+
+81+%2B+30+=+111+
+111+=+111+
OK
