Question 60741: Employees of a discount appliance store receive an additional 20% off of the lowest price on an item. If an employee purchases a dishwasher during a 15% off sale, how much will he pay if the dishwasher originally cost $450? Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! (.85*450)(.8)=382.50*.8=$306.00 FOR THE DISHWASHER AFTER THE 15% & THE 20% DISCOUNTS

there are many ways to solve these type of word problems.
I choose the "lazy method=fewer numbers & calculations".
For discounts the best was is to directly calculate the new price by subtracting the 15% discount (as a percent) 1-.15=.85 then multiply the price by .85 to get the dicounted price
450*.85=$382.5 now this is also dicounted by 20% or (1-.2=.8)
382.50*.8=$306.00. I choose to combine these two operations into one formula thus
(450*.85).8=$306
