Question

Piper has a loyalty card good for a 9% discount at her local hardware store. if the total cost, before tax and discount, of all the items she wants to buy is cc, which expression represents the cost after the discount

Answer 1

To find the cost after a 9% discount, we multiply the total cost c by 0.91, which represents the remaining percentage after the discount is applied. The expression for the discounted price is 0.91 * c.

Step-by-step explanation:

The question asks about applying a discount to the total cost of items. If Piper has a loyalty card that gives her a 9% discount at a hardware store, and the total cost of the items is represented by c, we need to calculate the cost after the discount is applied.

To calculate the discount amount, we convert the 9% discount to decimal form by dividing 9 by 100, which gives us 0.09. We then multiply this decimal by the total cost c to find the discount amount: 0.09 * c.

To find the final price after the discount, we subtract the discount amount from the total cost: c - (0.09 * c). This gives us 0.91 * c, which is the expression for the cost after the discount.
