2x^5+12x^4+16x^3-12x^2-18x+9=0

24702x + 9

Step-by-step explanation:

First, put everything you need to in parenthisis.

(2x^4) + (12x^4) + (16x^3) - (12x^2) - (18x + 9)

Then Simplifly

32x + 20736x + 4096x - 144x -18x + 9

Now Simplifly everything one by one

20768x + 4096x - 144x - 18x + 9

24864x - 144x - 18x + 9

24720x - 18x +9

24702x + 9

Now you can stop there, or solve for X by dividing each # by 24702

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
