Problema Solution
A store has clearance items that have been marked down by 30%. They are having a sale, advertising an additional 20% off clearance items. What percent of the original price do you end up paying?

Let 'x' represent the original price.
After 30% mark down the price will be: (1 - 0.3) = 0.70x
After additinal 20% on 0.70x the new price will be: (1 - 0.20)^0.70x = 0.80*0.70x = 0.56x
You will end up paying 56% of the original price.
