1 Answer

  • Answer:

    $12.85

    Step-by-step explanation:

    First we need to find the sale price of the CD

    Sale price = old price - old price * discount rate

                     = 17 - 17* .3

                     = 17 - 5.1

                     = 11.9

    The sale price of the CD is 11.90

    Now we need to find the tax

    tax = sale price of cd * tax rate

          = 11.9 * .08

          = .95


    The final cost of the CD is  sale price of CD plus the tax

    Total cost = sale price of CD + tax

                     = 11.90 + .95

                        =12.85
