The expression that represents the final price of the DVD is 0.9064y

How to determine the final cost?

The given parameters are:

  • Discount = 12%
  • Sales tax = 3%
  • Original price = y

The final cost is calculated using:

Final = Original price * (1 - discount) * (1 + sales tax)

So, we have:

Final = y * (1 - 12%) * (1 + 3%)

Evaluate the expression

Final = 0.9064y

Hence, the expression that represents the final price of the DVD is 0.9064y
