Calculation of Change with Explanation

To calculate the change the customer should receive, we need to determine the total cost of the 10 plates and subtract it from the amount the customer paid.

The original price of the plate is 80 rubles, and it is being sold with a 10% discount. To calculate the discounted price, we can multiply the original price by 0.9 (100% - 10% = 90%):

Discounted price per plate = 80 rubles * 0.9 = 72 rubles.

Since the customer bought 10 plates, the total cost of the plates is:

Total cost of plates = 10 plates * 72 rubles = 720 rubles.

The customer paid the cashier 1000 rubles, so to calculate the change, we subtract the total cost of the plates from the amount paid:

Change = Amount paid - Total cost of plates = 1000 rubles - 720 rubles = 280 rubles.

Therefore, the customer should receive 280 rubles in change.

Please let me know if there's anything else I can help#### Calculation of Change To calculate the change the customer should receive, we need to determine the total cost of the 10 plates and subtract it from the amount the customer paid.

The original price of one plate is 80 rubles, and it is being sold with a 10% discount. Therefore, the discounted price of one plate is 80 - (10% of 80) = 80 - 8 = 72 rubles.

The total cost of 10 plates at the discounted price is 10 * 72 = 720 rubles.

The customer paid 1000 rubles to the cashier.

To calculate the change, we subtract the total cost from the amount paid: 1000 - 720 = 280 rubles.

Therefore, the customer should receive 280 rubles in change.

Answer: The customer should receive 280 rubles in change.
