Answer:
First find what the sale price of the CD is. 30% off means the CD is selling for 70% of the original cost ( 100%-30% = 70%)
Multiply the original cost by 70%:
17.00 x 0.70 = $11.90 ( sale price)
Now you need to multiply the sale price by the tax percentage to find the amount of tax:
11.90 x 0.08 = 0.95 ( tax)
Now add the sale price and the tax for the total cost:
11.90 + 0.95 = $12.85
