Answer:
50%
Step-by-step explanation:
After a reduction by 33 1/3%, the price is 66 2/3% = 2/3 of its original value. To bring it back to 1 times the original value, it must be multiplied by the reciprocal of 2/3, that is, it must be multiplied by 3/2 = 1.50 = 1 +50%.
The price must be increased by 50% to bring it back up to $540.

Answer:
A trinomial
Step-by-step explanation:
Since there are three terms, x^2, 3x, and 8, it is a trinomial
Multiply everything in the second parenthesis by x.
-3x^3 + 3x^2 + x
Multiply everything in the second parenthesis by 2.
-6x^2 + 6x + 2
Combine these two equations together.
-3x^3 + 3x^2 + x - 6x^2 + 6x + 2
Combine like terms.
-3x^3 - 3x^2 + 7x + 2
Hope this helps!
