3) Employees receive 20% off the lowest price of an item.  If an employee buys a dryer during a 15% sale, how much will he pay for a dryer that originally cost $450?

15% = 15/100 = 0.15;  20% = 20/100 = 0.2

450 - 0.15(450) we subtract the 15% discount to know the new lesser price

450 - 67.50 = 382.50

382.50 - 0.2 (382.50) we subtract the 20% employee discount from the new price to know the employee price

382.50 - 76.50 = 306

So employees will pay $306
