The expression \(0.90(d - 5)\) refers to the total cost of the **jewelry** present after applying a discount.
Here's how to break it down:
- \(d\) represents the original cost of the jewelry.
- The expression \(d - 5\) indicates that there is a discount of $5 on the original cost of the jewelry.
- The term \(0.90(d - 5)\) means that after applying the $5 discount, the remaining amount is then subject to a 10% discount (hence the multiplication by 0.90).
So, the expression \(0.90(d - 5)\) ultimately calculates the total paid for the jewelry after applying both the $5 discount and the 10% discount on the remaining amount.
