Calculating the Cost of One Book

To calculate the cost of one book, we can use the information provided. The total cost of 8 identical books is 1000 rubles, and the amount received after the purchase is 328 rubles.

Using this information, we can calculate the cost of one book as follows:

Step 1: Calculate the cost of 8 books: - Total cost of 8 books = 1000 rubles. - Total cost of 8 books = 328 rubles + cost of 8 books. - Cost of 8 books = 1000 - 328 = 672 rubles.

Step 2: Calculate the cost of one book: - Cost of 1 book = Cost of 8 books / 8 = 672 / 8 = 84 rubles.

Therefore, one book costs 84 rubles.

This calculation is based on the provided information and the formula for finding the cost of one item when the total cost and quantity are known
