Final answer:
The total price of the CD, including tax, is $8.90.
Step-by-step explanation:
To find the total price of the CD, including tax, we need to first calculate the discounted price of the CD. If the CD is 30% off, the discounted price would be 30% of $12.00, which is $3.60. So the discounted price of the CD would be $12.00 - $3.60 = $8.40.
Next, we need to calculate the sales tax on the discounted price. The sales tax is 6% of $8.40, which is $0.50.
Finally, to find the total price of the CD including tax, we add the discounted price and the sales tax. So the total price would be $8.40 + $0.50 = $8.90.
