FINAL TEST NOTE PAGE

I need a note page that will assis me in passing a proctored final test.  Itmust be very clear as my memory is not going to be good.  I have attached the review final test that should be similar to the test I will take. I know it is bad but I just cannot seem to grasp math very good.  I am hoping to be able to change numbers and work the formulas.  Help me if you can.

I am putting $20 because it doesnt give the opportunity to say 20 + depnding on the work.  There should be a check box for a bonus for supberb work.

Thanks for looking.
