Answer 2

Calculation of the Cost of Books for Children and Adults

To calculate the difference in the amount paid for books for children and adults, we need to determine the cost of books for each category.

Given that the total cost of books purchased for the library is 48,000 rubles, and the cost of books for children is 3/12 of this amount, while the cost of books for adults is 5/12 of this amount, we can calculate the following:

- Cost of books for children: (3/12) * 48,000 = 12,000 rubles [[1]](https://www.academia.edu/43456250/%D0%9D%D0%B5%D0%BF%D1%80%D0%B0%D0%B2%D0%B8%D1%82%D0%B5%D0%BB%D1%8C%D1%81%D1%82%D0%B2%D0%B5%D0%BD%D0%BD%D1%8B%D0%B5_%D0%BE%D1%80%D0%B3%D0%B0%D0%BD%D0%B8%D0%B7%D0%B0%D1%86%D0%B8%D0%B8_%D0%9A%D0%B0%D0%B7%D0%B0%D1%85%D1%81%D1%82%D0%B0%D0%BD%D0%B0_%D0%BD%D0%B5%D0%BA%D0%BE%D1%82%D0%BE%D1%80%D1%8B%D0%B5_%D0%BF%D1%80%D0%B0%D0%B2%D0%BE%D0%B2%D1%8B%D0%B5_%D0%BE%D1%81%D0%BD%D0%BE%D0%B2%D1%8B_%D1%84%D1%83%D0%BD%D0%BA%D1%86%D0%B8%D0%BE%D0%BD%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F_NON_GOVERNMENTAL_ORGANIZATIONS_OF_KAZAKHSTAN_LEGAL_FOUNDATIONS_OF_THEIR_OPERATION). - Cost of books for adults: (5/12) * 48,000 = 20,000 rubles.

Calculation of the Difference in Cost

To find the difference in the amount paid for books for adults compared to books for children, we subtract the cost of books for children from the cost of books for adults:

- Difference in cost = Cost of books for adults - Cost of books for children - Difference in cost = 20,000 - 12,000 = 8,000 rubles.

Therefore, the library paid 8,000 rubles more for books for adults than for books for children.
