A store has clearance items that have been marked down by 55%. They are having a sale, advertising an additional 60% off clearance items. What percent of the original price do you end up paying?
Call the original price P
A markdown of 55% means it is worth 45% of P
And a markdown of another 60% means it is worth 40% of P(.45)
So
P (.45) ( .40) = .18P
You end up paying 18% of the original price
