To determine if the cashier is using percentages correctly, we need to calculate the total reduction in price based on the given percentages.Let's assume the original price of the item is
100 = 0.40 *
40 - The reduced price is
40 =
60 = 0.30 *
18 - The final price after the second reduction is
18 =
100- The final price after both reductions is
100 -
58Therefore, the actual percent reduction from the original price is:- (
100) * 100% = 58%So, the correct answer is:B. The cashier is not using percentages correctly. The actual percent reduction from the original price is 58%.
