Final answer:

The price of each CD before tax is found by subtracting the total sales tax from the total amount paid and dividing by the number of CDs. Lisa's total sales tax for 3 CDs was $3.60. The final price of each CD before tax was $10.70.

Step-by-step explanation:

To calculate the price of each CD before tax, we first need to subtract the total sales tax from the total amount paid. Lisa paid $35.70 for 3 CDs, including sales tax, and each CD had an additional $1.20 of tax.

  1. Calculate the total sales tax for 3 CDs:
    $1.20 tax per CD × 3 CDs = $3.60 total tax.
  2. Subtract the total sales tax from the total amount paid to find the total price before tax:
    $35.70 total paid - $3.60 total tax = $32.10.
  3. Divide the total price before tax by the number of CDs to find the price per CD:
    $32.10 ÷ 3 CDs = $10.70 per CD before tax.

Thus, the price of each CD before tax was $10.70.
