The original price is 30$ because we know that the new price is worth 60% of the old price. We can set up an equation to model this: 0.60x = 18. Dividing both side by 0.60 gives us an original value of 30. If you take 40% off of 30 you get 18 — allowing us to check our work.
<span>x^3 - 3(x)^2 + x - 3 < 0
х</span>²(х-3)+(х-3)<0
(x-3)(x²+1)<0
x²+1 always more than zero
therefore (x-3)(x²+1)<0 when x-3<0, x<3
Answer: 6.416%
