You can put this solution on YOUR website!
Let +y+ = total value in dollars
Let +x+ = number of each type of coin
+y+=+.05x+%2B+.1x+%2B+.25x+
+y+=+.4x+
----------------
check:
suppose the are +10+ of each type
of coin
+y+=+.05%2A10+%2B+.1%2A10+%2B+.25%2A10+
+y+=+.5+%2B+1+%2B+2.5+
+y+=+4+
and
+y+=+.4x+
+y+=+.4%2A10+
+y+=+4+
OK
