Today, I would like to talk to you about a product that not only helps us keep our stationery organized, but also contributes to environmental protection. That product is the recycled paper pen box.
As we all know, paper is one of the most commonly used materials in our daily lives. However, the production of paper consumes a large amount of natural resources and energy, and also generates a significant amount of waste and pollution. Therefore, it is important for us to find ways to reduce our consumption of paper and to recycle it whenever possible.
The recycled paper pen box is a great example of how we can contribute to this effort. Instead of using new paper to make the pen box, this product is made from recycled paper, which helps to reduce the demand for new paper and the associated environmental impact. In addition, the production process for the recycled paper pen box consumes less energy and generates less pollution compared to the production of new paper products.
Furthermore, the recycled paper pen box is not only environmentally friendly, but also practical and durable. It provides a convenient and organized way to store and carry pens, pencils, markers, and other stationery items. Its sturdy construction and attractive design make it a great addition to any desk or workspace.
In conclusion, the recycled paper pen box is a simple yet effective way for us to contribute to environmental protection in our daily lives. By choosing products made from recycled materials, we can help reduce the demand for new resources and minimize the environmental impact of our consumption. I encourage all of you to consider using the recycled paper pen box and other recycled products whenever possible. Thank you for your attention.

Với 90000 đồng, Lan mua được số hộp sữa là:
\(90000:5000=18\left(hộp\right)\)
18 hộp rỗng đổi được số hộp sữa là:
\(18:5=3\left(dư3\right)\)
Vậy 18 hộp rỗng sẽ đổi được 3 hộp sữa và còn dư 3 hộp rỗng, tổng là 6 hộp
6 hộp đổi được số hộp sữa là: 6 : 5 = 1 (dư 1)
Tổng số hộp sữa Lan có là: 18 + 3 + 1 = 22 (hộp)
Đáp số: 22 hộp sữa
