Cameron goes to a store and buys an item that costs xx dollars. He has a coupon for 10% off, and then a 8% tax is added to the discounted price. Write an expression in terms of xx that represents the total amount that Cameron paid at the register.

1 answer

To find the total amount Cameron paid at the register after applying the 10% discount and then adding 8% tax, we can break it down into steps.

  1. Calculate the discount:
    The discount on the item is 10% of the original price \( x \).
    Discount = \( 0.10x \)

  2. Calculate the discounted price:
    The price after applying the discount is:
    Discounted price = \( x - 0.10x = 0.90x \)

  3. Calculate the tax on the discounted price:
    The tax is 8% of the discounted price.
    Tax = \( 0.08 \times (0.90x) \)
    Tax = \( 0.072x \)

  4. Calculate the total amount paid:
    The total amount paid is the discounted price plus the tax:
    Total Amount = \( \text{Discounted Price} + \text{Tax} \)
    Total Amount = \( 0.90x + 0.072x \)
    Total Amount = \( 0.972x \)

Thus, the expression representing the total amount that Cameron paid at the register is:
\[ 0.972x \]
