A television set that retails for $600 is markdown by 20%. at checkout, an additional 20% is marked off the price of the tv. Find the final selling price of the television set.
i added 20%+20%=40% so you turn 40% into.40 then you multiply 600×.40 to get 240 since it is discounted you have to subtract so you subtract 600-240 to get 360 which is your final product
