Work:
A 12-pack of boxes is 4 3-pack of boxes, I found this by dividing 12 by 3.
A 24-pack of boxes is 2 12-pack of boxes, found by dividing 24 by 12.
A 24-pack of boxes is 8 3-pack of boxes, found by dividing 24 by 3 or by multiplying the two previous together (sometimes may not work)
Multiply
$1.09 × 4
That gets you to $4.36, which is less than the price of a 12-pack of boxes.
Then, multiply
$4.39 × 2
That gets you $8.78, which is less than a 24-pack of boxes.
Finally, multiply
$1.09 × 8
That gets you $8.72, which is less than a 24-pack of boxes.
Answer:
The best to buy is the 3-pack of boxes of juice, because it is cheaper when buying multiple of the 3-packs than it is to buy one or more of the 12-pack or 24-pack.
Hope this helps anyone with the question.

Answer:
x = 5/4 + √65/4 or x = 5/4 - √65/4
Step-by-step explanation:
I'm assuming you mean 2x^2-5x-5=0?
x = ( -b ± √b^2 - 4ac ) / 2a
x = ( -(-5) ± √(-5)^2 - 4(2)(-5) ) / 2(2)
x = ( 5 ± √(25 + 40) ) / 4
x = ( 5 ± √65 ) / 4
x = 5/4 ± √65/4
Therefore, x = 5/4 + √65/4 or x = 5/4 - √65/4
