Answer 1

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
