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.

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.

So what you want to do is divide the cost by the amount of juice boxes you're getting, so for the first one you want to divide 1.09/3 to get the cost for one box of juice, then for the second 4.39/12 and 8.79/24 to see which is the lowest price per box.1.09/3=0.36333333333 rounded to 0.364.39/12=0.36583333333 rounded to 0.37
8.79/24=0.36625 rounded to 0.37
The answer is the pack of 3 boxes of juice because it is the cheapest price because its 0.36 while the other two are 0.37.

Answer from: Quest

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

Answer from: Quest

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200. after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes 1800 - 6400 which gets you 11,600.
