Stacked Discount
The second discount only applies to what is left after the first, so 30% plus 20% is 44% off, not 50%.

What it means
The real discount is 44%, not the 50% you get by adding — a gap of 6 points.
Formula
Final price = List price × (1 − Percentage/100) × (1 − Rate/100)
Swapping the order changes nothing — it is multiplication, so the final price is identical either way.
