Answer: the total price of the CD, including tax, is approximately $16.07.
Explanation:
To find the total price of the CD, including tax, we need to follow these steps:
1. Calculate the discount:
- The CD is 10% off, so we need to find 10% of the original price ($17.00).
- To calculate this, we multiply the original price by 10% (or 0.10): $17.00 x 0.10 = $1.70.
2. Calculate the discounted price:
- Subtract the discount amount from the original price: $17.00 - $1.70 = $15.30.
- The discounted price of the CD is $15.30.
3. Calculate the sales tax:
- The sales tax is 5% of the discounted price.
- To calculate this, we multiply the discounted price by 5% (or 0.05): $15.30 x 0.05 = $0.765.
- Rounding this amount to two decimal places, the sales tax is approximately $0.77.
4. Calculate the total price:
- Add the discounted price and the sales tax: $15.30 + $0.77 = $16.07.
- The total price of the CD, including tax, is approximately $16.07.
