It sounds like they started out with a
price +p+, then they took 10% off it,
so it cost +p+-+.1p++=+.9p+, then they
decided to take 15% off of that, so it
cost +.9p+-+.15%2A.9p+=+.9p%2A%28+1+-+.15+%29+
+.9p%2A%28+1+-+.15+%29+=+.85%2A.9p+
+.85%2A.9p+=+.765p+
---------------------
That's what you ended up paying, so
+.765p+=+306+
+p+=+306%2F.765+
+p+=+400+
The original price was $400
-------------------------
check:
+.9%2A400+=+360+
+.85%2A360+=+306+
OK
