Answer:
D. $306.
Step-by-step explanation:
If the dishwasher originally cost $450, then after applying 15% off, its price will be 100% - 15% = 85% of the original price:


Thus, during the 15% off sale, the dishwasher will cost $382.5.
Now, the employees of the discount appliance store receive an additional 20% off; therefore, the price of the dishwasher will be 100% - 20% = 80% of $382.5:


Therefore, the employee will purchase the dishwasher at a price of $306, which is choice D.
