Final answer:
When you receive a 30% off coupon after already getting a 30% off sale, the discount is not equal to a 60% discount.
Step-by-step explanation:
When you receive a 30% off coupon after already getting a 30% off sale, the discount is not equal to a 60% discount. To understand why, let's consider an example:
Let's say the original price of an item is $100. With the 30% off sale, the price becomes $70. Applying the 30% off coupon to the new price of $70, the discounted price would be $49. The total discount is $51, which is not equal to a 60% discount.
