I think that the answer is 45% because the sale started off with a 20% discount, but at the end they added another 25% to the sales. So since the sale already started off with 20%, you add 20%+25% which equals 45%.
Think about c/3 =4/1 and apply the cross multiplication rule since those two fractions are equal.
We get c•1= 3•4
c=12
