You can put this solution on YOUR website!
Let +a+ = Jenny's age now
Let +b+ = her dad's age now
--------------------------------
(1) +a+=+b+-+28+
(2) +a+%2B+b+=+60+
-------------------------
Plug (1) into (2)
(2) +b+-+28+%2B+b+=+60+
(2) +2b+=+88+
(2) +b+=+44+
-------------------------
Dad is 44
---------------
check:
(1) +a+=+b+-+28+
(1) +a+=+44+-+28+
(1) +a+=+16+
and
(2) +a+%2B+b+=+60+
(2) +16+%2B+44+=+60+
(2) +60+=+60+
OK
