Final Grade Calculation

So, I had a C- for my Calculus class for my midterm grade and I took the final exam last Friday that is worth 30%. The quizzes are 20%, exams are 30%, workbook is 10%, and mylabsplus is 10%. Before the exam, I had a C average and if the final is worth 30%, will my grade move up a letter grade?
Please help.

You should be able to calculate this yourself using a calculator or Excel.
