Calculation of the Price Increase per Book

To calculate how much each book has increased in price, we can use the information provided. The school initially planned to purchase 80 identical textbooks for 240 rubles. However, they were only able to buy 60 textbooks. We need to find out how much the price of each book increased.

Let's calculate the initial price per book: 240 rubles / 80 books = 3 rubles per book.

Now, let's calculate the final price per book: 240 rubles / 60 books = 4 rubles per book.

To find out how much the price increased, we subtract the initial price per book from the final price per book: 4 rubles per book - 3 rubles per book = 1 ruble increase per book.

Therefore, each book has increased in price by 1 ruble.

Answer

Each book has increased in price by 1 ruble.
