*i really need it explained and the answer, i can't do math to save my life and it is killing me. i've done all kinds of programs and such, just can't seem to keep any math in my brain.

            The Cost of a Basic Car: $10,150.00
Options on the Cost of a Basic Car: $738.00
           License and Registration Fee: $50.00
                                      Subtotal: $10,938.00
                                              Sales Tax: 0.06
                                           Total: $11,594.28

I notice that I have to add the cost of the car, the option of the car, the license and registration fee, and the sales tax in order to find out the total of what it might cost for all of them. So I calculated it in a receipt form to find of the subtotal and the total of Ray' s cost, which is above the screen.
