Answer:
$126
Step-by-step explanation:
90 x 1.40 = $126 = 40% profit of cost.
126 / 0.90 = $140 original price before 10%

proof 140 x 0.10 = $14
140 - 14 = $126 the price wanted.
Answer:
f(x) = (x − 1)(x − 2)(x − 3)
Step-by-step explanation:
through the x axis at one; x = 1 factor (x - 1)
through the x axis at two; x = 2 factor (x - 2)
through the x axis at three; x = 3 factor (x - 3)
f(x) = (x − 1)(x − 2)(x − 3)
