Question: A dress is marked at $200. If it has a 30% discount followed by an additional 10% discount, what is the final price?

Options:

Correct Answer: $140

Solution:

First discount: 200 - (30/100 * 200) = 200 - 60 = $140. Second discount: 140 - (10/100 * 140) = 140 - 14 = $126.

A dress is marked at $200. If it has a 30% discount followed by an additional 10% discount, what is the final price?

Step 1: Start with the original price of the dress, which is $200.
Step 2: Calculate the first discount of 30%. To do this, multiply the original price by 30% (or 0.30). So, 30% of $200 is 0.30 * 200 = $60.
Step 3: Subtract the first discount from the original price. So, $200 - $60 = $140. This is the price after the first discount.
Step 4: Now, calculate the second discount of 10% on the new price of $140. To do this, multiply $140 by 10% (or 0.10). So, 10% of $140 is 0.10 * 140 = $14.
Step 5: Subtract the second discount from the price after the first discount. So, $140 - $14 = $126. This is the final price of the dress.
