To determine if the cashier is using percentages correctly, we need to calculate the total percentage reduction from the original price after both discounts are applied.Let's assume the original price of the item is
100 =
100 -
702. The second discount is 40% off the reduced price: - 40% of
28 - The reduced price after the second discount is
28 =
100, and the final price after both discounts is
100 -
58.To find the percentage reduction, we divide the total reduction by the original price and multiply by 100:- Percentage reduction = (
100) * 100 = 58%Therefore, the correct answer is:B. The cashier is not using percentages correctly. The actual percent reduction from the original price is 58%.
