Final answer:

To find the total amount that Mason paid at the register, multiply the original price by 0.749.

Step-by-step explanation:

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

  1. Calculate the amount of discount Mason received using the coupon. This can be done by multiplying the original price (x dollars) by 30% or 0.3: 0.3x.
  2. Subtract the discount amount from the original price to get the discounted price: x - 0.3x = 0.7x.
  3. Calculate the amount of tax to be added to the discounted price. Multiply the discounted price by 7% or 0.07: 0.07 * 0.7x = 0.049x.
  4. Add the tax amount to the discounted price to get the total amount that Mason paid: 0.7x + 0.049x = 0.749x.

Therefore, the expression that represents the total amount that Mason paid at the register is 0.749x dollars.
