Question

Nathaniel goes to a store an buys an item that costs xx dollars. He has a coupon for 40% off, and then a 7% tax is added to the discounted price. Write an expression in terms of xx that represents the total amount that Nathaniel paid at the register.

Answer 1

To find the total amount Nathaniel paid at the register, subtract 40% of xx from xx to get the discounted price, then calculate the 7% tax on the discounted price and add it to the discounted price.

Step-by-step explanation:

To find the total amount Nathaniel paid at the register, we need to follow these steps:

1. Subtract 40% of xx from xx to find the discounted price. This can be expressed as: xx - (0.4 * xx).
2. Next, calculate the 7% tax on the discounted price. Multiply the discounted price by 0.07 to find the tax amount. This can be expressed as: (xx - (0.4 * xx)) * 0.07.
3. Finally, add the tax amount to the discounted price to get the total amount Nathaniel paid at the register. The expression representing this is: (xx - (0.4 * xx)) + ((xx - (0.4 * xx)) * 0.07).
