Answer:
8 dollars and 30 cents.
Step-by-step explanation:
Take .50 and multiply that by the 6 CDs you bought. It comes out to 3 dollars. Then, take 67.80 and divide that by 6 and you get 11 dollars and 30 cents, now take the total tax off, which is 3 dollars, and now, each CD is 8 dollars and 30 cents before tax.
