Step-by-step explanation:
(8x^3-5x-1)-(7x^2+6x-10)
remove unnesasary ( )
8x^3-5x-1 -(7x^2+6x-10)
the distribute
8x^3-5x-1 -7x^2-6x+10
combine like terms
8x^3-11x+9-7x^2
use the communative property to reorder the equation

just normal addition
If you mean the price is now 120% of the original, $<span>4.74 (3.95 * 0.8) is the new price.
If you mean the price is now 80% of the original, $3.16 (3.95 * 1.2) is the new price.</span>
