Question : 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 : I believe I need to have 1 more question to answer, as the additional discount can be added with the 15% off on the lowest price, or the additional discount is applied after the 15% is off from the lowest price. I'll illustrate how the 2 methods of calculation will come up with 2 different net prices. 1) discount rate: 15%+20%=35% off. 450 - (450x35%) = 450 - 157.5 = 292.5 (net price) 2) discount rate: first 15%, then 20% 450 - (450x15%) = 450 - 67.5 = 382.5 382.5 - (382.5x20%) = 382.5 - 76.5 = 306 (net price)

Question : how to solve a problem like: x+3(x+4)=20.
what are the steps to solve this problem?
Answer : You need to distribute.... X+3(X+4)=20 X + 3X + 12 = 20 //distributed 3 among what is in the parenthesize 4X + 12 = 20 //simplify 4X = 8 //subtract 12 X = 2 //simplify My YouTube: http://www.youtube.com/FilmingHumor/
