PlEASE HELP I ADDED PIC. Which inequality is represented by the number line

It is C.

Step-by-step explanation:

2x−1≥9(Possibility 1)

2x−1+1≥9+1(Add 1 to both sides)

2x≥10

2x

2

≥

10

2

(Divide both sides by 2)

x≥5

2x−1≤−9(Possibility 2)

2x−1+1≤−9+1(Add 1 to both sides)

2x≤−8

2x

2

≤

−8

2

(Divide both sides by 2)

x≤−4

x≥5 or x≤−4

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 !
