  • Answer:

    She paid = $33

    Step-by-step explanation:

    First we need to find the new price after markup

    The original price is 15

    100% markup means double the price

    New price = original price + original price * mark up rate

                         =15 + 15 * 1.00

                          =30

    New price is 30

    Now we need to find the sales tax, which is the price times the tax rate

    sales tax = 30* .10

                  = 3


    The final cost = price + sales tax

                            = 30 +3

                               = 33
