.56p
p*.80 (20 percent off)*.70(30 percent off)=.56p (56 percent of the retail price)
If the retail price or p has a value of 100, then the regular price which is 80% of that is 80.
So the regular price is 80 and so the sale price which is 70% of that is 56.
So the retail price is 100 and the sale price is 56. Therefore it is 0.56p.
