A CD usually sells for $17.00. If the CD is 30% off, and sales tax is 8%, what is the total price of the CD, including tax?

Mademuasel [1]

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
