Problem Analysis

To solve this problem, we need to calculate the amount of change the buyer will receive after purchasing 20 notebooks at a price of 17 rubles per notebook, with a payment of 500 rubles.

Solution

To find the total cost of the notebooks, we multiply the price per notebook by the number of notebooks purchased: Total cost of notebooks = 20 notebooks * 17 rubles/notebook = 340 rubles.

To find the amount of change the buyer will receive, we subtract the total cost of the notebooks from the payment made: Change received = Payment - Total cost of notebooks = 500 rubles - 340 rubles = 160 rubles.

Therefore, the buyer will receive 160 rubles in change.

Conclusion

The buyer will receive 160 rubles in change after purchasing 20 notebooks at a price of 17 rubles per notebook, with a payment of 500 rubles.
