Given that a<span>
local RadioShack store wants to buy a new line of plasma TVs.
Manufacturer A offers chain discounts of 18/12, and Manufacturer B
offers terms of 17/13.
Let the list price of the plasma TVs be x, then after a chain discount of 18/12 by Manufacturer A, the selling price of the plasma TVs will be (1 - 0.18)(1 - 0.12)x = 0.82(0.88)x = 0.7216x
Also, after the discount of 17/13 by manufacturer B, the selling price of the plasma TVs will be (1 - 0.17)(1 - 0.13)x = 0.83(0.87)x = 0.7221x
Thus, the final selling price after discount by manufacturer A is 0.7216 and the final selling price after dscount by manufacturer B is 0.7221x.
Therefore, Manufacturer A offers a </span><span>single equivalent discount rate that is the best deal.</span>

Answer: Graph D
Step-by-step explanation: Got it right on plato
You haven't shown us his answer or any of his work, so we don't know
whether it was right or wrong, and we have no way to find his mistake
if his work was wrong.
(10 discs) / (5.49 dollars) = (10/5.49) disc/dollar = 1.821 disc per dollar
(5.49 dollars) / (10 discs) = (5.49/10) dollar/disc = 0.549 dollar per disc
The answer is C.
x=2
y=-30
(2;-30)
