Question 60741
(.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
