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.<br /><br />Let's assume the original price of the item is $100.<br /><br />1. The first discount is 30% off the original price:<br /> - 30% of $100 = $30<br /> - The reduced price after the first discount is $100 - $30 = $70<br /><br />2. The second discount is 40% off the reduced price:<br /> - 40% of $70 = $28<br /> - The reduced price after the second discount is $70 - $28 = $42<br /><br />Now, let's calculate the total percentage reduction from the original price:<br />- The original price is $100, and the final price after both discounts is $42.<br />- The total reduction is $100 - $42 = $58.<br /><br />To find the percentage reduction, we divide the total reduction by the original price and multiply by 100:<br />- Percentage reduction = ($58 / $100) * 100 = 58%<br /><br />Therefore, the correct answer is:<br />B. The cashier is not using percentages correctly. The actual percent reduction from the original price is 58%.
