The jeans are discounted at $10%$ off.

$45 is what percent of $50

$$45 = n%($50)$

$($45)/($50) = (n%cancel($50))/(cancel($50))$

$.90 = n%$

$90% = n$

Since the original price of $50 represents the 100% price
and $45 represents 90% of that price the discount is

$100% - 90% = 10%$

The jeans are discounted at 10% off.
