Final answer:
To calculate the price after a markdown of 30 percent, subtract 30 percent of the original price from the original price. In this case, the original price is RM40, so the price after the markdown is RM28.
Step-by-step explanation:
To calculate the price after a markdown of 30 percent, we need to find 30 percent of the original price and subtract it from the original price. The original price is RM40, so 30 percent of RM40 is (30/100) * RM40 = RM12. The price after the markdown is RM40 - RM12 = RM28.
Step-by-Step Calculation:
Calculate 30% of RM40:
30% of RM40 = 0.30 × RM40 = RM12.
Subtract the markdown from the original price:
RM40 - RM12 = RM28.
Therefore, the price of the toothbrush after a 30 percent markdown is RM28.
