The cost of gold in the alloy:
+2.7g+
The cost of silver in the alloy:
+5%2A%2815+-+g%29+
-----------
+%28+2.7g+%2B+5%2A%2815+-+g%29%29+%2F+15+=+164+
+%28+2.7g+%2B+75+-+5g+%29+%2F+15+=+164+
+-2.3g+%2B+75+=+15%2A164+
+-2.3g+=+2460+-+75+
g is going to end up negative. I think
you have the price of gold and the
price of silver reversed.
