Answer 2

To solve this problem, we need to calculate the total amount of money that can be obtained from selling the waste paper and compare it to the cost of the books.

Given: - The cost of the books is 300 UAH. - Each student is asked to bring 4 kg of waste paper. - Waste paper is bought at a rate of 2 UAH per 1 kg.

Calculating the total amount of money from selling the waste paper:

To find the total amount of money that can be obtained from selling the waste paper, we need to multiply the weight of the waste paper brought by each student by the rate at which it is bought.

- Each student brings 4 kg of waste paper. - The rate at which waste paper is bought is 2 UAH per 1 kg.

So, the total amount of money from selling the waste paper is calculated as follows: 4 kg * 2 UAH/kg = 8 UAH per student.

Determining if the money from selling the waste paper is enough to buy the books:

To determine if the money obtained from selling the waste paper is enough to buy the books, we need to compare the total amount of money from selling the waste paper to the cost of the books.

- The total amount of money from selling the waste paper is 8 UAH per student. - The cost of the books is 300 UAH.

To find out if the money is enough, we divide the cost of the books by the amount of money obtained from selling the waste paper: 300 UAH / 8 UAH per student = 37.5 students.

Since we cannot have a fraction of a student, we need to round up to the nearest whole number. Therefore, we need at least 38 students to bring waste paper in order to have enough money to buy the books.
