(1) x = 20. After the first discount the price was 160*0.8=$128, so already less than $130. Sufficient.
(2) y = 15. If x=0% and y=15%, then the answer is NO but if x=50% and y=15%, then the answer is YES. Not sufficient.

This is a typical C trap here that one must avoid. I guess the problem would have been tougher if they gave 'y' first
