Answer:
The cost of the CD's next week after the additional 25% markdown can be calculated as follows: 1. Calculate the sale price of the CD this week by applying the 20% discount: - Original price of the CD: $9.99 - Discounted price: $9.99 - (20% of $9.99) = $9.99 - $1.998 = $7.992 2. Calculate the final price of the CD next week by applying the additional 25% markdown to the sale price: - Sale price this week: $7.992 - Discounted price next week: $7.992 - (25% of $7.992) = $7.992 - $1.998 = $5.994 Therefore, the cost of the CD's next week after the additional 25% markdown will be $5.994.
