Question 546025: I HAVE AN 83% IN MY CLASS, AND I'M GETTING READY TO TAKE THE FINAL THAT IS WORTH 12.5% OF MY GRADE. THE LOWEST GRADE THAT I CAN GET TO PASS THE CLASS IS A 78. COULD YOU TELL ME WHAT I NEED TO GET ON THE TEST IN ORDER TO END UP WITH A 78% IN THE CLASS. I JUST WANT TO FIGURE OUT THE WORST POSSIBLE SCENARIO!

Answer by Edwin McCravy(20056) (Show Source): You can put this solution on YOUR website!

Your exam counts 12.5% so your average of 83% counts 100%-12.5% or 87.5%

Let x = your exam grade

(87.5%)(83%) + (12.5%)(x) = 78%

    (.875)(.83) + (.125)x = .78

           .72625 + .125x = .78

                    .125x = .05375

                        x = .43 or 43%

You only have to make a 43 to pass.
