The original price of a certain TV set is discounted by s percent, and the reduced price is then discounted by 2s percent. If P is the original price of the TV Set, which of the following represents the price of the television set after the two successive discounts?	Options.
A) P(1 - 0.03x + 0.02x^2)
B) P(1 - 0.03s + 0.0002s^2)
C) P(1 - 0.03x + 0.002x^2)
D) P(1 - 2x^2)
E) P(1 - 3x + 2x^2)
Youcansolve this problem with number plugging.   Say the original price was $10 and s=50. Then after the first reduction the price would become $5 and after the second reduction of   2*50=

<output>100</output>
100% the rprice would become $0.   Now, since P is not zero, then the expression in the brackets must be zero for s=50. Only answer choice B works.   Answer: B.   On this problem - number pluggin is not giving me the answer.. I initially used s = 10, then 2s = 20 and P = 100. Answer should after both consecutive discounts = 72. I plug in the respective values and I keep getting 68. Can you double check my math.   100 (1-0.03(10) + 0.0002 (10)^2)   100 (1-0.3 + 0.0002 (100))   100 (0.7 + 0.02)   100 (0.68) = 68????   double check my math. Am I missing something? I also plugged in your numbers and still did not get zero as final answer with choice P(1 - 0.03s + 0.0002s^2)..
