+50+-+%28+3n+%2B+5%2A2+%29+ = change she received
+50+-+3n+-+10+
+40+-+3n+
-----------------------
check:
Suppose +n+=+3+
+40+-+3n+=+40+-+9+
+40+-+3n+=+31+
$31 change received
and
+50+-+%28+3n+%2B+5%2A2+%29+
+50+-+%28+3%2A3+%2B+5%2A2+%29+
+50+-+%28+9+%2B+10+%29+
+50+-+19+=+31+
$31 change received
OK
