Question

Jack goes to a store an buys an item that costs � x dollars. He has a coupon for 15% off, and then a 4% tax is added to the discounted price. Write an expression in terms of � x that represents the total amount that Jack paid at the register.

Answer 1

To calculate the total amount that Jack paid at the register, we need to follow these steps:

Step 1: Calculate the discount
The coupon gives a 15% discount, so the discounted price will be:
Discounted price = x - 0.15x
Discounted price = 0.85x

Step 2: Add tax
A 4% tax is added to the discounted price, so the total amount paid will be:
Total amount paid = (0.85x) + (0.04 * 0.85x)
Total amount paid = (0.85x) + (0.034x)
Total amount paid = 0.884x

Therefore, the expression in terms of x that represents the total amount that Jack paid at the register is 0.884x.
