Introduction

In this article, we will explore the problem of packing 25 pages into the fewest number of packages. This problem is a classic example of a combinatorial optimization problem, which involves finding the optimal solution among a set of possible solutions. We will use mathematical techniques to find the most efficient way to pack the pages.

Understanding the Problem

Brian is trying to find the total number of stickers in 8 bags and 25 pages. He wrote the following answer in the place-value chart:

{ \begin{tabular}{|c|c|c|c|} \hline A) 2 books and 5 pages & \end{tabular} }

However, this problem is not about finding the total number of stickers, but rather about packing 25 pages into the fewest number of packages.

Packing Pages with the Fewest Packages

To pack 25 pages into the fewest number of packages, we need to find the optimal way to divide the pages among the packages. One way to approach this problem is to use the concept of bin packing.

Bin Packing

Bin packing is a problem in which we need to pack a set of items (in this case, pages) into a set of bins (in this case, packages) of limited capacity. The goal is to minimize the number of bins used.

Mathematical Formulation

Let's denote the number of pages as $n$ and the capacity of each package as $c$ . We want to find the minimum number of packages $m$ needed to pack all $n$ pages.

Optimal Solution

To find the optimal solution, we can use a greedy algorithm. The idea is to pack each page into the first package that has enough capacity.

Algorithm

Sort the pages in non-increasing order of their sizes.
Initialize an empty list of packages.
For each page, find the first package in the list that has enough capacity. If no such package exists, create a new package.
Add the page to the package.
Repeat steps 3-4 until all pages have been packed.

Example

Let's consider an example with 25 pages of sizes 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, and 25.

Step 1: Sort the pages

Page	Size
1	1
2	2
3	3
4	4
5	5
6	6
7	7
8	8
9	9
10	10
11	11
12	12
13	13
14	14
15	15
16	16
17	17
18	18
19	19
20	20
21	21
22	22
23	23
24	24
25	25

Step 2: Initialize the list of packages

Package	Capacity
1	0

Step 3: Pack each page

Page	Size	Package
1	1	1
2	2	1
3	3	1
4	4	1
5	5	1
6	6	1
7	7	1
8	8	1
9	9	1
10	10	1
11	11	1
12	12	1
13	13	1
14	14	1
15	15	1
16	16	1
17	17	1
18	18	1
19	19	1
20	20	1
21	21	1
22	22	1
23	23	1
24	24	1
25	25	1

Step 4: Repeat steps 3-4

In this example, we can see that all 25 pages can be packed into a single package of capacity 25.

Conclusion

In this article, we have explored the problem of packing 25 pages into the fewest number of packages. We have used a greedy algorithm to find the optimal solution, which involves packing each page into the first package that has enough capacity. We have also provided an example to illustrate the algorithm. The optimal solution in this case is to pack all 25 pages into a single package of capacity 25.

Discussion

The problem of packing pages with the fewest packages is a classic example of a combinatorial optimization problem. It has many applications in real-world scenarios, such as packing boxes, shipping goods, and scheduling tasks. The greedy algorithm used in this article is a simple and efficient way to solve this problem. However, there are other algorithms and techniques that can be used to solve this problem, such as dynamic programming and branch and bound.
