<span>10.SHOPPING 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.</span>1.09/3=0.36333333333 rounded to 0.364.39/12=<span>0.36583333333 rounded to 0.37 </span>8.79/24=<span>0.36625 rounded to 0.37 </span><span>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.</span>
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.
