You can put this solution on YOUR website!
Let +x+ = amount Mary spends
+2x+-+5+ = amount Danny spends
--------------------------------------
+x+%2B+2x+-+5+=+70+
+3x+-+5+=+70+
+3x+=+75+
+x+=+25+
and
+2x+-+5+=+2%2A25+-+5+
+2x+-+5+=+50+-+5+
+2x+-+5+=+45+
---------------------------
Mary spends $25
Danny spends $45
----------------------
check:
+25+%2B+45+=+70+
+70+=+70+
OK
