Answer 1

The best description of the total cost for ordering DVDs from the website, given by the expression 14.95x - 5.95, is that each DVD costs $14.95, and there is a $5.95 discount applied to the entire order.

Step-by-step explanation:

The expression 14.95x − 5.95 represents the total cost, in dollars, of ordering x DVDs from a website. To determine which option best describes the cost for a DVD website order, let's examine each term in the expression separately.

The first term, 14.95x, indicates that each DVD costs $14.95. Since the x represents the quantity of DVDs ordered, we multiply the cost per DVD by the number of DVDs. This is a variable cost that changes with the quantity purchased.

The second term, − 5.95, is a constant and does not depend on the number of DVDs ordered. This indicates a one-time fee or discount applied to the entire order. Given it's a negative value, it reduces the total cost, suggesting a discount is applied to the order.

Therefore, the option that best describes the cost for a DVD website order is: Each DVD costs $14.95, and there is a $5.95 discount per order (Option B).
