You can put this solution on YOUR website!
Let +x+ = score needed on the final math test
in order to average 90
-------------------------------
+%28+95+%2B+87+%2B+85+%2B+93+%2B+94+%2B+x+%29+%2F+6+=+90+
+%28+454+%2B+x+%29+%2F+6+=+90+
+454+%2B+x+=+6%2A90+
+x+=+540+-+454+
+x+=+86+
Annie needs 86 on the last test
